He died at Ambalakaadu in Thrissur, Kingdom of Cochin (now a part of the state of Kerala), and is buried at St. Francis Xavier's Church, Sampaloor, where his tomb can be seen. Robert Caldwell, one of the eminent Tamil liguistics and historians, in his book 'A Political and General History of Tinnevelly (present Tirunelveli) in the Presidency of Madras: From the Earliest Period to the Cession to the English Government in AD 1801' opines that, based on the writings of his biographer and the letters written to Europe at the same time, "It is certain from authentic records that Beschi was "Rector" of Manapar (present Manapad) in 1744 and that he died there in 1746. This was in the 66th year of his age and the 40th of his residence in India. It is very probable that Manapar was the first place in the Tamil country where Beschi resided after he left Goa, in consequence of which he might naturally wish to end his days there." He, in the same book (page 243) further states that his body was laid in rest in the oldest church of Manapad which has been now completely buried in the sand.
