The Portuguese legacy of Bengal is still palpable in the heart of Kolkata, but sadly, it is overlooked and not paid the respect it deserves. Astonishing as it may sound, an attempt to murder, or at least a street fracas between two Europeans in colonial Calcutta, indirectly gifted this city a huge edifice — the Portuguese Church of the Sacred Heart of the Jesus. In Calcutta, 1821, near Old Chowringhee Theatre, a man named Luis De Souza openly fired inside a horse carriage, seriously injuring one Joseph Gonsalves. De Souza was arrested and an attempt to murder case was filed against him. Hearing this, his mother began praying for his life and made a resolution to build a church if her prayers were answered. Her son escaped capital punishment, but was imprisoned for a decade. After De Souza was released, she laid the first stone of the church on February 12, 1832. The church was completed in two years and its consecration was held on Easter Sunday, March 30, 1834.

The Tipu Sultan Shahi Mosque (also known as Tipu Sultan Masjid) is a famous mosque in Kolkata, India named after Tipu Sultan the ruler of Mysore. The mosque is a relic of architectural and cultural heritage. The Mosque was built by his 11th son Prince Gholam Mohammed. He was the ruler of Mysore but why his youngest son built this mosque in memory of his father, far away from Mysore here in Calcutta. There is a history behind this. Tipu Sultan, the ruler of the South Indian Deccani Kingdom of Mysore, was engaged in a series of wars with the British East India Company. After the last war, with Tipu's death on the battlefield and six years after Tipu's death, the entire family was exiled to Calcutta by the British Government. During that period the capital of Mysore Srirangapatnam was captured by British Army. Son of Tipu Sultan, Gholam Mohammed was a child when arrived in Calcutta. He was a man of varied qualities.
