The Iron Age grave sites at Sankert are listed as a Swiss heritage site of national significance.

The graves are located in a group of tumuli on the eastern edge of the lower Biber valley at the foot of the Schienerberg. The first discovery of the graves was in 1836 by Ferdinand Keller. In 1846 and 1856 there were further excavations by Johann Conrad Fehrlin. Additional excavations happened in 1874-75 by the preacher Julius Müller, 1894 by Ferdinand Schalch. In 1912-13 there was an unauthorized dig by Joseph von Sury and Bertram Böschenstein, then in 1943 Walter Ulrich Guyan explored the entire site and further digs occurred in 1967 and 1978.

The group contains at least 35 tumuli. Some of the graves contain items from the 8th through 6th Centuries BC Hallstatt culture, while others are from the 5th and 4th Century BC La Tène culture. Each of the bodies was buried with personal items including jewelry, eating utensils and weapons. Many were also buried with food and drink in ceramic vessels. Due to the numerous excavations and limited records, many of the items can not linked to a specific grave. The location of the village that was associated with these graves is unknown.
