Trinitatis Church is part of the 17th century Trinitatis Complex, which includes the Rundetårn astronomical observatory tower and the Copenhagen University Library, in addition to the church. Built in the time of Christian IV, the church initially served the students of Copenhagen University.
The interior was seriously damaged in the fire of 1728 but was rebuilt in 1731. The bases and capitals of the columns and arches were repaired. All wood furnishings were replaced, and the floor was covered with tiles from Öland. The reconstruction was in Northern Gothic-Baroque style. The church was rededicated October 7, 1731 and the remains of the university library were moved again. The furnishings were renewed with an altarpiece and pulpit by Friederich Ehbisch (1731) and a large Baroque clock (1757). The church was refurbished in 1763.
References:The Gravensteen is a castle in Ghent originating from the Middle Ages. The name means 'castle of the counts' in Dutch. Arnulf I (918–965), Count of Flanders, was the first to fortify this place, building a medieval bastion on this high sand dune, naturally protected by the river Leie and its marshy banks. This bastion consisted of a central wooden building and several surrounding buildings, also in wood.
In the early 11th century, the wooden building was replaced by a stone residence, consisting of three large halls that made up three storeys, connected by a stone stairwell. The monumental stone staircase, the light openings, the fireplaces built into the walls and the latrines were signs of considerable luxury and comfort in those days. There was probably also a tower.
