There are a lot of Zamindar Houses in Calcutta, which are historical and heritage too. These are very attractive and still carry the essence of old (ancient) times.
Zamindar baris, or the homes of wealthy landlords, are a part of Kolkata's heritage. Here are some zamindar baris in Kolkata and nearby:
Marble Palace A majestic palace on Muktaram Babu Street that is home to a family. The palace is open to visitors, and you can get a guided tour from the guards and errand boys. The palace is known for its art, including paintings by Rubens, and its music room with a collection of birds.
The Rajbari Bawali A 300-year-old heritage resort that offers a luxurious experience. The resort is located about an hour and a half from Kolkata.
Chowdhury Zamindar Bari A 375-year-old house surrounded by mango orchards, ponds, temples, and a Durga Mancha. The house is located in Nimo and offers a time-traveling experience for guests.
Itachuna Rajbari A zamindar bari in Kolkata that some say is reasonably value-for-money.
The zamindari system was abolished in 1955, but the zamindars were the main revenue collectors for the British and Mughal administrations.
Many other Zamindar Bari(Houses) like Shiva Bazar Rajbari, Khelat Ghosh's Bari, Laha's House etc etc. With ancient style structure and architecture, they're really an attraction of Calcutta.
