The Martinikerk (Martin's church) is the oldest church in Groningen. The church and its associated tower (the Martinitoren) are named after Saint Martin of Tours (316–397), the patron saint of the Bishopric of Utrecht to which Groningen belonged. The church was a cathedral for a short period during the first bishopric of Groningen (1559–1594).
The origins of the Martinikerk are a cruciform church built in the 13th century, which was extended in the 15th and 16th centuries. It contains several 16th century tombs and Wessel Gansfort's 18th century tomb. Much of the wall and roof paintwork has been preserved. Of particular note is a 16th-century depiction of the life of Jesus Christ.
The tower was built from 1469 till 1482, with later additions. Citizens of Groningen often refer to the tower as d'Olle Grieze (Old Grey One). The original 13th century tower was destroyed by lightning and a new tower was built in the 15th century, also destroyed by lightning.

Edfu was one of several temples built during the Ptolemaic Kingdom, including the Dendera Temple complex, Esna, the Temple of Kom Ombo, and Philae. Its size reflects the relative prosperity of the time. The present temple initially consisted of a pillared hall, two transverse halls, and a barque sanctuary surrounded by chapels. The building was started during the reign of Ptolemy III Euergetes and completed in 57 BC under Ptolemy XII Auletes. It was built on the site of an earlier, smaller temple also dedicated to Horus, although the previous structure was oriented east–west rather than north–south as in the present site.
