Aalborghus is a half-timbered castle built by King Christian III from 1539 to around 1555 initially as a fortification. Soon it became the seat of the king's provincial governors in Northern Jutland, and after the introduction of absolutism, became used by the State County of Northern Jutland for taxes.
A building had pre-existed at the site before Christian III's castle. It stood south of the castle and is mentioned in the first documentation of Aalborghus, dating back to 1340. It was owned by Margrethe I and was the death place of King Hans in 1513 who died in a horse riding accident.
Frederick I had originally intended to destroy the initial building around 1530 and moving to a different site to convert Aalborg's Franciscan monastery into a castle. However he left the decision to his son Christian III, who later decided to demolish the original in 1539 and contracted the royal architect Morten Bussert to build a new fortified castle north of the old site, near the Liim Fjord. A barrier wall was built alongside the fjord, and later in 1633, Christian IV built a north wing facing the port, which was used as a granary for the storage of food supplies such as corn. A western wing was built to the same effect later, holding other supplies such as meats and fish.
The southern facing wing was created between 1808 and 1809 but all that remains today of the original castle is the east wing. Between 1954 and 1964 the old granaries underwent full renovation by the Royal Inspector of Listed Buildings, Leopold Teschl, who converted them into council offices.References:
The Château Comtal (Count’s Castle) is a medieval castle within the Cité of Carcassonne, the largest city in Europe with its city walls still intact. The Château Comtal has a strong claim to be called a 'Cathar Castle'. When the Catholic Crusader army arrived in 1209 they first attacked Raymond-Roger Trencavel's castrum at Bèziers and then moved on to his main stronghold at Carcassonne.
The castle with rectangular shape is separated from the city by a deep ditch and defended by two barbicans. There are six towers curtain walls.
The castle was restored in 1853 by the architect Eugène Viollet-le-Duc. It was added to the UNESCO list of World Heritage Sites in 1997.
