Atop the 76 metre high mount where St. Thomas was martyred, is an old church, which was built by the Portuguese around 1514. Among the interesting relics in the church is an old stone cross which the apostle is said to have clutched in his hand while dying.

The blood-like stains on the cross have given the name 'Bleeding Cross' and the mystic stains have to this day been found to be too deep to be removed by scrubbing. On the wall above the altar is an oil painting of the Madonna which was brought to India by St. Thomas and is said to be one of the seven that were painted by St. Luke.
