 It served as a new office and residence for the Bernese Landvögte after the destruction of the previous building dating to the 14th century in a fire in 1518.In contrast to the other buildings, the Landvogt's residence does not back directly up to the ring wall, but is separated from it by a 1 to 2-metre gap.The exception is a small round tower at the southeast corner; built in 1626, it replaced a protruding bay that served as an outhouse.
