Der Aa-kerk

The Martinikerk (Martin's church) is the oldest church in Groningen, Netherlands. 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 (the 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. Its organ contains stops dating back to 1450, and was rebuilt and enlarged by Arp Schnitger among others. The church and organ are filmed extensively in the documentary Martinikerk Rondeau.

The west gallery organ of the Martinikerk in Groningen dates from the 15th century; it took its present form in the 18th century when it was expanded by Arp Schnitger, his son Franz Caspar Schnitger and his successor Albertus Antonius Hinsz. It has 52 speaking stops on three manuals and pedal, and is one of the largest and most famous baroque organs in Northern Europe.

The Goudkantoor (English: Gold Office) is a building built in 1635 and located on Waagstraat near the Grote Markt (Main Square) in Groningen, Netherlands. Originally it was built as an office for the receiver of the province of Groningen when it was called Collectehuis. The text on the building, Date Caesari quae sunt Caesaris (Latin) (English: Render unto Caesar that which is Caesar's) refers to the original function. The coat of arms of the city of Groningen is located on the building. The name Goudkantoor goes back to 1814-1887, when the Waarborgbureau voor Goud- en Zilverwerken was located in the building. Gold and silver could get a hallmark so people could prove it was real. Prior to World War II the Northern Ship Transport was located in the building. Just before the liberation of the city, in April 1945, the entire collection was transferred to a building on the north side of the Grote Markt, because the owners were afraid that the Goudkantoor would get damaged during the liberation, but in fact it was one of the few buildings that wasn't heavily damaged, because fire-fighters saved it from burning down.After the war, the museum was located in the building again for a short time and later it was used as an information centre (Het Stadjershuis) and as a tourist information centre. The Goudkantoor was restored during the construction of the Nieuwe Waagstraat and is currently a restaurant.
