St Ib's Church (Danish: Sankt Ibs Kirke) is a Romanesque church in Roskilde on the Danish island of Zealand.
Located on a small rise between Roskilde Fjord and the old town, the church is built on a site where there was originally a wooden church which was revealed in archaeological digs in the 1980s and 1990s.
[2] It was built of travertine limestone in about 1100 and originally consisted of a nave and a chancel with flat ceilings, extending over a length of 22 m (72 ft).
In the 13th century, six tall slender windows were added as well as a tower and a porch.
[3][4] Today the church, which is no longer functional, again has a flat wooden ceiling.
