The church of St. Wystan at Repton in Derbyshire, England with parts of the upstanding masonry belong to the pre-Conquest period. There is an 8th-9th century crypt, the only English example of that date supported on four central columns. Repton is known to be the burial place of the Mercian kings and recent excavations have found evidence of a mausoleum outside the main building, as well as evidence of the Viking encampment of 867.
