Lohagarh Fort, which was constructed by Jat ruler Maharaja Suraj Mal in the 18th century, is one of the finest architectural monuments in Rajasthan. Though the fort is not associated with richness, it depicts an atmosphere of strength and glory as it once featured a highly creative defense system that protected it every time. It was in fact named as the Lohagarh Fort, or Iron Fort, due to its invincibility at the time when British attempted to conquer it.One of the strongest forts ever built in Indian history, Lohagarh Fort has two gates; Ashtdhaatu (eight-metalled) to the north and Chowburja (four-pillared) to the south. The fort encompasses three palaces; Mahal Khas, Kamra Mahal and Purana Mahal. Of these, the Kamra Palace now serves as the State Archaeological Museum. The sandstone durbar, which was once Maharajas meeting hall, has also been transformed into a museum, lately.The government museum within the fort exhibits articles like weapons and safety shields. Antiques such as hunted animals, wood articles, jewellery boxes and ornaments are also displayed here. Between the museum and the main entrance lies the Nehru Park, where visitors can just sit and enjoy. The fort is surrounded by deep moats that once thwarted at least four British attempts to lay siege to the Iron Fort.Two towers, Jawahar Burj and Fateh Burj, which were constructed within the walls of the fort for celebrating the victories over Mughals and British, still stand erect. Moti Mahal was constructed to commemorate the victory of the king. Inscribed with the genealogy of the Jat kings, an iron pillar called Vijay Stambha (Victory Column) stands erect in the palace complex. The complex of Iron Fort also houses a Ganga Temple and a Laxman Temple.An art gallery housed inside the fort exhibits specimens of miniature paintings on peepal leaves, mica and old lithopapers. Old portraits of the Maharajas of Bharatpur are also displayed at this gallery. At the upper storey of the gallery is the Armoury section, displaying various types of guns and miniature cannons. Tourists can travel to Lohagarh Fort using any of the local transport modes, be it bus, auto rickshaw or cycle rickshaw.
