Roman Catholic St. Bartholomew's Cathedral (Frankfurter Dom, or Dom St. Bartholomäus), was built of red sandstone in Gothic style between the 13th and 15th centuries, and at 95 meters, still manages to stand out in this city of skyscrapers. One of only a handful of churches in Germany to be designated as an Imperial Cathedral, it was here from 1562 to 1792 that the coronation of Emperors took place in the Election Chapel. Beneath the tower is the magnificent Crucifixion by Hans Backoffen, sculpted in 1509, while in the Marienkapelle is the Maria-Schlaf-Altar from 1434. Other highlights include the grave-slab of King Günter von Schwarzburg who died in Frankfurt in 1349, as well as numerous carved side altars dating from the 15th and 16th centuries. The cathedral's most important relic is the skullcap of St. Bartholomew, kept in the Late Romanesque Bartholomew's Choir.
