The area once known as ‘Lal Dighi’ (Red Lake) and later Tank Square, became Dalhousie Square in the 1850s, named after Lord Dalhousie, the British Governor General. It was later renamed Benoy–Badal–Dinesh Bag (BBD Bag) in honor of three Indian nationalist martyrs. This heritage walk offers a fascinating glimpse into Kolkata’s 18th and 19th-century history and architecture. Starting from the Governor’s House (Raj Bhavan), it passes the Treasury Building, St. John’s Church, Kolkata General Post Office (GPO), Collectorate Office, and the Writer’s Building. Next, visit St. Andrew’s Kirk, Old Court House Street, the Old Currency Building, Postal Sorting Office, and Central Telegraph Office. A detour to Wellesley Place (now Red Cross Place) leads to the Great Eastern Hotel, bringing you full circle near Curzon Park.

Raj Bhavan is the official residence of the Governor of West Bengal, built in 1803 during British rule.

St. John’s Church, built in 1787, is one of the oldest churches in Kolkata.

Surrounded by peaceful gardens, the church offers a glimpse into the city’s British past and early Christian heritage.

The Calcutta High Court, established in 1862, is the oldest High Court in India. Its striking Gothic-style architecture, inspired by a courthouse in Belgium, makes it a prominent landmark in Kolkata. Located near the city’s central administrative area, it stands as a symbol of justice and colonial heritage. Visitors can admire its majestic exterior while exploring the historic district nearby.

Town Hall, built in 1813, is a grand colonial building that once served as a meeting place for the British elite. Designed in Roman-Doric style, it now houses a museum showcasing Kolkata’s rich history and cultural heritage. Located near the High Court and Raj Bhavan, it’s a must-visit for those interested in the city’s colonial past and architectural elegance.

The Writers’ Building, constructed in 1777, was originally built for clerks—or “writers”—of the British East India Company. Located in the heart of B.B.D. Bagh, this imposing red-brick structure later became the secretariat of the West Bengal government. Though not open to the public, its grand colonial architecture and historic significance make it a notable landmark in Kolkata.
