Located some 28 kilometres north west of Tây Ninh provincial town in Xóm Mới Village, Tân Phong Hamlet, Tân Biên District, Chót Mạt Tower is one of only three surviving Khmer structures left in Việt Nam. Believed to date from the 8th century, the pre-Angkorian brick and sandstone tower was first recognised as an important vestige by French archaeologist de Laponguière, who in 1911 placed the tower on a list of 14 important monuments in Cochinchina. Minor restoration work was carried out during the 1930s, and excavations took place at the site in 1992 revealing Hindu statues and other important artefacts. The tower was extensively reconstructed in 2002. Chót Mạt originally comprised two towers; the ruins of the second tower, located next to the surviving tower, are preserved under a protective canopy. Pending further archaeological investigation, Chót Mạt Tower forms the northernmost component of a wider network of Khmer temples which stretched some 70 kilometres south along the banks of the Vàm Cỏ Đông River as far as Tây Ninh Province's southern border with Long An Province, where Tây Ninh Province's other surviving prasat, Bình Thạnh Tower, is located. Other Khmer or proto-Khmer vestiges dotted around Tây Ninh Province include four tower bases at Long Khánh and Long Thuận (Bến Cầu District), one tower base at Tiên Thuận (Bến Cầu District), plus as yet unidentified ruins at Phước Chỉ (Trảng Bàng District), Phước Trạch (Gò Dầu District), Thanh Điền (Châu Thành District) and Hiệp Ninh (Hòa Thành District).
