Bhismaknagar Fort, in Lower Dibang Valley district of Arunachal Pradesh, is a brick-built ruin near Roing that the Archaeological Survey of India links to the early Chutia (Sutiya) rulers of the Sadiya region. It is a quiet, little-visited archaeological site rather than a restored monument, and a trip here pairs naturally with the hills and lakes around Roing. This guide gathers the verified basics: how to reach it, the permits you need, what survives on the ground, and when to go.
Bhismaknagar Fort is an early-medieval fortified brick complex about 30 km from Roing, the Lower Dibang Valley district headquarters in eastern Arunachal Pradesh. The Archaeological Survey of India ascribes the remains to the Chutia rulers of Sadiya and dates their rule from the 11th to the 16th century CE. Indian visitors need an Inner Line Permit; foreigners need a permit from the Ministry of Home Affairs.
Key takeaways
- Bhismaknagar Fort sits about 30 km from Roing in Lower Dibang Valley, Arunachal Pradesh; there is no air or rail service in Roing, so you arrive by road.
- The ASI Guwahati Circle ascribes the brick remains to the Chutia (Sutiya) rulers of Sadiya, dated 11th–16th century CE; the district administration records a plinth area of 1,860.52 sq m.
- The nearest airport is Dibrugarh (Mohanbari) in Assam, roughly 150 km away; the nearest railhead is Tinsukia, reached via the Bhupen Hazarika Setu over the Lohit River.
- Indian citizens need an Inner Line Permit (tourist e-ILP, ₹300 for up to 3 days and ₹500 for 4–14 days as of October 2026); foreign nationals need a permit from the MHA.
- Best visited October to April; the monsoon makes the approach roads slippery, according to the Lower Dibang Valley administration and Incredible India.
- The name recalls the legend of King Bhishmaka, father of Rukmini, though the standing remains are ascribed to the Chutia period, not the legend.
About Bhismaknagar Fort: quick facts
Bhismaknagar Fort is a group of brick-built structures enclosed by a fortified rampart wall, set on low ground backed by the Mishmi Hills in Lower Dibang Valley district, Arunachal Pradesh. The Archaeological Survey of India describes it as the capital of the Chutia dynasty, with two impressive gateways on the eastern and western sides.
According to the Lower Dibang Valley district administration, the central brick structure covers a plinth area of 1,860.52 sq m and has three halls, two extension rooms and six entrances in all. A rampart wall of brick, stone and mud protects nearly the whole complex, with the hills forming a natural barrier to the north.
Do not confuse this site with the town of Bhismaknagar as a civic place name or with other legend-linked “Bhishmak” sites elsewhere in the country. For travel purposes, the fort is reached from Roing, the district headquarters.

History, the Chutia link and the Rukmini legend
The remains at Bhismaknagar are generally ascribed to the rule of the Chutias (Sutiyas), a Tibeto-Burman group who ruled the Sadiya region, according to the ASI Guwahati Circle. The ASI dates that rule from the 11th to the 16th century CE and records that the Chutia rulers traced their ancestry to Bhishmaka, the legendary king after whom the site is named.
The site was first explored by I. Block in 1848, and the Research department of the Government of Arunachal Pradesh excavated it between 1965 and 1970, according to the district administration. The digs yielded wheel-turned pottery, terracotta plaques with animal and floral designs, decorative tiles, figurines of horse and elephant, and inscribed bricks.
The name “Bhismaknagar” ties the place to a legend. According to local belief and the Rukmini–Krishna story, the site was the seat of King Bhishmaka, father of Rukmini, who married Krishna. This is legend, not documented history; the standing brick remains are attributed to the Chutia period. Scholars have also connected the wider capital region to the Chutia king Lakshminarayana, whose name appears on an inscribed brick from the ruins.
The fort has suffered from neglect. Press reports over the past decade, including from the Arunachal Observer and Business Standard, have described the site as deteriorating and called for restoration, and the ASI has been urged to maintain the centrally significant monument. Expect ruins and interpretation signage rather than a polished heritage park.
Best time to visit Bhismaknagar Fort
The best time to visit Bhismaknagar Fort is October to April, when the weather is pleasant and the approach roads are easier. According to Incredible India and the Lower Dibang Valley administration, the monsoon brings heavy rain that makes travel difficult and the roads slippery, so the wet months are best avoided.
Post-monsoon weeks in October and November bring clear air and green hills; December to February is cold, with snow possible up at Mayudia (about 56 km from Roing, at nearly 8,000 ft / 2,440 m). Carry warm layers if you combine the fort with a Mayudia trip in winter.
| Season | Months | What to expect |
|---|---|---|
| Post-monsoon | October–November | Clear skies, green hills, comfortable days — a strong window |
| Winter | December–February | Cold; snow possible at Mayudia; dry roads; pack warm layers |
| Spring | March–April | Warm and pleasant; good light; generally good roads |
| Monsoon | May–September | Heavy rain, slippery roads, possible landslips — avoid |
How to reach Bhismaknagar Fort
You reach Bhismaknagar Fort by road from Roing, about 30 km away; there is no air or rail service at Roing itself, according to the district administration. Hire vehicles are available from Roing, Tezu, Tinsukia and Dibrugarh, and shared taxis run from Roing towards the fort area.
By air: The nearest airport is Dibrugarh (Mohanbari) in Assam, roughly 150 km away, with flights to major Indian cities. From there you drive to Roing via Tinsukia and the Bhupen Hazarika Setu (the Dhola–Sadiya bridge over the Lohit River, India’s longest river bridge at about 9.15 km). Dibrugarh’s airport is officially still listed under that name as of early 2026.
By rail: The nearest major railhead is Tinsukia (New Tinsukia) in Assam; the ASI’s own access note lists New Tinsukia railway station. Road distances from Tinsukia to Roing are reported in the region of 100–120 km (sources vary — reconfirm locally), continuing over the Bhupen Hazarika Setu.
By road: Most travellers reach Roing by shared or hired vehicle from Tinsukia or Dibrugarh, then arrange a local taxi for the fort. Roads are generally serviceable outside the monsoon.
| From | Distance (approx.) | Notes |
|---|---|---|
| Roing (district HQ) | About 30 km | Taxi or shared vehicle; base for the visit |
| Tinsukia railhead (Assam) | About 100–120 km | Via Bhupen Hazarika Setu; sources vary |
| Dibrugarh (Mohanbari) airport | Roughly 150 km | Via Tinsukia and the Dhola–Sadiya bridge |
| Mehao Lake / Sanctuary | About 17 km from Roing | Easy add-on from the same base |
What to see at the site and around Roing
At Bhismaknagar Fort you see fortified brick ramparts, the eastern and western gateways, and the plinth of a large brick hall complex rather than tall standing walls. The ASI records two impressive gateways; the district administration notes three halls, two extension rooms and six entrances within a plinth of about 1,860 sq m.
Allow roughly one to two hours to walk the ruins and read the interpretation boards. Because excavation has been limited and the site is weathered, treat it as an atmospheric archaeological ruin and a window into the Chutia past, not a reconstructed fort.
Roing makes the natural base, and the fort fits well alongside its lakes and viewpoints. If you are planning a wider Arunachal trip, this eastern circuit is very different in feel from the western monastery country around Tawang — see our Tawang travel guide for that side of the state.
| Spot | Distance from Roing | Why go / time needed |
|---|---|---|
| Bhismaknagar Fort | About 30 km | Chutia-era brick ramparts and gateways; 1–2 hours |
| Mehao Lake and Wildlife Sanctuary | About 17 km | Clear forest lake; rich biodiversity; half a day |
| Mayudia | About 56 km | Mist, forest and mountain views at ~8,000 ft; day trip |
Suggested itinerary
A two-day base at Roing covers the fort comfortably and leaves room for the lakes and hills. Add a day if you want to go up to Mayudia or deeper into the Dibang Valley.
- Day 1: Arrive Roing from Tinsukia or Dibrugarh over the Bhupen Hazarika Setu; settle in; a short visit to Mehao Lake (about 17 km) if time allows.
- Day 2: Early drive to Bhismaknagar Fort (about 30 km); 1–2 hours at the ruins; return to Roing for lunch; optional afternoon exploring the town.
- Day 3 (optional): Day trip to Mayudia (about 56 km) for mist and mountain views; carry warm clothing.
Where to stay
Stay in Roing, which has hotels, guesthouses and homestays; there is no formal accommodation at the fort itself. Options are modest rather than luxury, so book ahead in the October–April season and for any festival dates.
- Budget (indicative ₹800–₹1,500 per night): Basic guesthouses and homestays in Roing town.
- Mid-range (indicative ₹1,500–₹3,500 per night): Better-equipped hotels and well-run homestays.
- Government/circuit options: Enquire about any state tourism or circuit-house rooms through the district administration or Arunachal tourism.
These are planning estimates for late 2026 and should be reconfirmed when you book; tariffs vary with season and demand.
Food to try
Food around Roing leans on rice, fresh river fish, leafy greens and locally raised meat, often lightly spiced. Try these where available, respecting that many dishes are tied to local Idu Mishmi and neighbouring communities:
- Bamboo-shoot preparations (fermented or fresh bamboo shoot cooked with meat or fish) — a staple sour-savoury flavour across the region.
- Smoked or river fish with greens — simple, fresh and common near the Dibang.
- Rice-based meals and local rice beer (apong, a traditional fermented rice drink) — offered on social occasions; accept or decline politely.
Carry snacks and water for the fort visit, as there are few eateries at the ruins.

Permits and rules
Every non-local visitor to Arunachal Pradesh needs an entry permit, and this applies to Bhismaknagar Fort. Indian citizens require an Inner Line Permit (ILP); foreign nationals require a permit from the Ministry of Home Affairs (commonly referred to as a Protected/Restricted Area Permit).
Indian visitors can use the state’s tourist e-ILP, launched in November 2022 and limited to Indian citizens. According to Arunachal tourism and MyGov, the tourist e-ILP covers stays of up to 14 days, with fees commonly listed at ₹300 for up to 3 days and ₹500 for 4–14 days (as of October 2026); longer stays need a provisional ILP. Apply online through the official Arunachal ILP portal and carry a printout plus a valid photo ID.
Foreign nationals cannot use the e-ILP system and must obtain their permit through the Ministry of Home Affairs or designated offices; rules and fees differ, so apply well ahead. For the site itself: it is a protected archaeological monument — do not climb on or remove bricks, do not deface surfaces, and follow any ASI or local signage. Respect local Idu Mishmi customs, ask before photographing people, and carry out your litter under the state’s plastic and eco rules.
Practical tips
Plan for a remote, low-infrastructure area and self-sufficiency around the fort. A few points worth knowing before you go:
- Connectivity: Mobile network and data can be patchy outside Roing town; download maps and permit documents offline.
- Cash and UPI: Carry enough cash; ATMs and reliable UPI are concentrated in Roing, and the fort area has no facilities.
- Transport: Arrange your taxi in Roing the evening before and agree the fare and waiting time for the fort day trip.
- Health: The nearest hospital services are in Roing; carry a basic kit, and plan for warm clothing if adding Mayudia in winter.
- Solo women: The area is generally calm; standard precautions apply, travel in daylight on the fort road, and keep your itinerary shared with your stay.
- Packing by season: October–April — layers and a light jacket; December–February — proper warm wear; avoid the monsoon for the slippery approach.
- Timings: Official hours are not published; travel listings cite roughly 8 am–5 pm — reconfirm at Roing before heading out.
