Goslar Cathedral, Romanesque collegiate church in Goslar, Germany

Goslar Cathedral was a three-nave, flat-roofed basilica with a double alternation of piers and columns, built of limestone blocks with red sandstone columns. Its westwork had two low octagonal towers and a stepped portal; three apses closed the east end, and a crypt lay under the choir. The surviving north porch, added around 1200, has two bays and a sculpted facade with two portals.

The cathedral arose between 1040 and 1050 as the focal point of the imperial residence area under Emperor Henry III. It was demolished in 1819, but the northern porch with its carved reliefs survived.

The church was dedicated to the apostles Simon and Jude, whose feast day of 28 October was Emperor Henry III's birthday in 1017; Abbot Meginher of Hersfeld gave him their relics for the foundation. The name Dom here means a collegiate church (Münster), not a bishop's seat. The bronze Krodo Altar and the 11th-century Imperial Throne, now in the Goslar Museum and the palace, came from its furnishings.

The only surviving section is the northern porch, which visitors can examine in the area of the former palace grounds. It is worthwhile to also visit the nearby St. Ulrich Chapel to gain a fuller understanding of the site's role in imperial history.

The English Wikipedia states that when Henry III died in 1056 his heart was buried within the walls of the collegiate church, not in St. Ulrich's Chapel. The church itself was auctioned in 1819 and quarried away by 1822, so the burial place lies under today's Kaiserpfalz car park, where the ground plan is marked in the paving.
