Built in Indo-Gothic style, in 1850, the St Mary’s Church is the oldest Roman Catholic church in the city. It was once the Vicariate of Hyderabad. The church’s curved arches and buttresses are praiseworthy. On the inside, it houses side altars for various saints and is adorned with four bells that were brought from Italy in 1901. A huge statue of the Virgin Mary holding Jesus in her arms greets the eyes as one enters the church. The Vatican has bestowed the church with a 'Minor Basilica' title, which is given to Roman Catholic churches based on the Canon Law.

Consecrated in 1813, the Church of St John the Baptist is the oldest church in the twin cities of Hyderabad and Secunderabad. It was set up to serve the needs of the British soldiers stationed at Lancer’s Line. It is one of the most popular spiritual sites of the city, where tourists often stop to admire the beautiful architecture and worship at the altar.

With a beautiful pink facade and arched windows with coloured glass, the All Saints Church was built in 1860 by the British who had settled in the cantonment of Secunderabad. It is situated in Trimulgherry and was mostly attended by members of the British army. It has now been converted into a tamil Anglican church and runs services in English and Tamil languages. The church boasts a stained-glass altar with Christ on the cross.
