Gobindgarh Fort gives Amritsar a major sight beyond the Golden Temple and border ceremony. The fort's history runs through Sikh rule, the era of Maharaja Ranjit Singh, and later military use, and recent restoration has turned it into a visitor complex with museums and performances.
It is more curated than atmospheric in places, but the scale and history are strong enough to justify a visit. Go for the broader Punjab story: arms, treasury legends, colonial pressure, and the transformation of a military site into public heritage.
