There is a combination of rounded and pointed arches in the transepts and crossing. The existing large square tower formed part of the church from the beginning, though it was raised in height at a later stage. The five eastern arches of the nave and their supporting pillars were built at the end of the 12th century, and have well-preserved capitals typical of the period. Although built at the same time, the arches of the northern side of the nave are different in type and have differently shaped columns and capitals. The three westernmost arches in the south arcade which have leafed and figured capitals were built after 1205, as was the west wall before the church was finally consecrated in 1218.
