 The bastion on the eastern perimeter of the inner bailey was constructed in 1642–46, replacing a curtain wall with battlements, to close the gap between the "Palas" and the Landvogt's residence and protect the castle from cannon bombardment from the Goffersberg.The adjacent residence was covered by a huge earthen embankment which absorbed moisture and rendered the building uninhabitable.In 1659, a clocktower was built on the east bastion; its pointed roof was replaced in 1760 with an onion dome.
