The Church of the Holy Ghost (Helligåndskirken) is one of the Copenhagen's oldest churches. The first abbey in Copenhagen was a Franciscan monastery founded in 1238, just 12 years after the death of Francis of Assisi. Prior to that, Archbishop Eskil had founded two Cistercian monasteries, Esrom Abbey and Herrevad Abbey. Typically for the order, they had been founded at more remote locations in Northern Zealand and Skåneland. At first, the new institution in Copenhagen was more of a hostal and workshop for travelling monks than a monastery proper. It was expanded on a number of occasions and remained the only monastery and a central part of the city's life for the next 250 years.
In 1296, a hospital was built by Roskilde Bishop Johannes Krag who was member of the powerful Krag-Hvide noble family. Johannes Krag's strict rule over the city had brought its population to an uprising. They attempted to storm Bishop's Palace at Slotsholmen and as part of a settlement, Krag agreed to build what was known as a House of the Holy Ghost. Such houses were facilities which cared for the sick, the poor and the old, more refuges for the weak and disabled than hospitals in the modern sense of the word.
The construction of the new building was to be paid for by the bishop and the citizens in equal shares. For its support, an annual ground rent was assessed all properties. Over the years, the hospital also received its own endowments, mainly of property, which provided income for its support. Next to the hospital a small church was built although it is not known exactly when it was added to the complex.
In 1469, King Christian I transformed the hospital into an abbey. Later, on his journey to Rome in 1474, Pope Sixtus IV acknowledged it as an institution under the Order of the Holy Ghost, with Santo Spirito in Rome as inspiration and mother church.
The abbey consisted of four wings around a courtyard. Of these the present-day church has evolved from the south wing while the House of the Holy Ghost is the former west wing. Originally the church did not have a tower. Construction of a tower was commenced in 1520 but before long the Reformation brought things to a standstill and in 1530 the abbey was decommissioned.
After the reformation the church was converted into a parish church. At the initiative of Christoffer Valkendorff, at that time Governor of Copenhagen, work on the tower was resumed in 1582. Brickwork was continued in another bond, making the transition between the old and the new part of the tower easily detectable. The tower was topped by a spire mounted in August 1594.References:
First record of Kastelholma (or Kastelholm) castle is from the year 1388 in the contract of Queen Margaret I of Denmark, where a large portion of the inheritance of Bo Jonsson Grip was given to the queen. The heyday of the castle was in the 15th and 16th centuries when it was administrated by Danish and Swedish kings and stewards of the realms. Kastelhoma was expanded and enhanced several times.
In the end of 16th century castle was owned by the previous queen Catherine Jagellon (Stenbock), an enemy of the King of Sweden Eric XIV. King Eric conquered Kastelholma in 1599 and all defending officers were taken to Turku and executed. The castle was damaged under the siege and it took 30 years to renovate it.
In 1634 Åland was joined with the County of Åbo and Björneborg and Kastelholma lost its administrative status.
