The Crestaulta and Cresta Petschna (a Bronze Age settlement), the
necropolis at Surin and the
double house at number 30 are listed as Swiss
heritage sites of national significance. Crestaulta is a significant Bronze Age site on a hill about west of Surin. It was discovered in 1935 and excavated by Walo Burkart in 1935–38. Three settlement phases were discovered. The bottom layer dates from the early Bronze Age (ca. 2000-1700/1600 BC) and included a number of post holes for simple huts with some attached
animal stalls. The hut was about . The second layer dates from the middle Bronze Age (1700/1600-1500/1400 BC) and consists of massive
dry stone walls, however there are no clear house or other building foundations. This layer also includes numerous animal stalls, a small round "cellar", part of a
kiln and fire pits. The upper layer is also from the middle Bronze Age (1500/1400-1300 BC) and includes an animal stall, a
menhir or standing stone and a wooden floor. Additional excavations have discovered
ceramic pots of a style that is now known as the
Inner-alpine Bronze Age culture () or formerly as the
Crestaulta-Kultur. In the river Cresta Petschna, about from Crestaulta a cemetery or necropolis was discovered in 1947. It included at least 11 early Bronze Age graves. The items buried in the graves (sewing needles,
pendants and arm rings) indicate that these were women's graves.
