Copenhagen Castle

Copenhagen Castle. A historic fortress and royal residence located on the island of Slotsholmen in central Copenhagen. Originally constructed in the 12th century, it served as a key defensive structure and the seat of Danish monarchs for centuries. The castle was demolished in the early 18th century to make way for the construction of the first Christiansborg Palace.

History

The castle's origins are traced to the foundational fortification built around 1167 by Absalon, the Bishop of Roskilde, who is credited as the founder of Copenhagen. This stronghold was established to protect the emerging trading port from Wendish pirates and rival powers like the Hanseatic League. The site was strategically chosen at the narrowest point of the Øresund, controlling maritime traffic. Over the following centuries, it was repeatedly expanded and reinforced by successive monarchs, including Eric of Pomerania and Christian I, reflecting its growing importance. It withstood several sieges, most notably during the Count's Feud in the 16th century, where it was captured by forces loyal to Christian III after a prolonged conflict. The castle later became a symbol of absolute monarchy under Frederick III, who was proclaimed hereditary king there in 1660 following the Treaty of Copenhagen.

Architecture

The architecture evolved from a medieval fortress into a complex Renaissance palace. The original Absalon's Castle was a relatively simple structure with high walls and a keep. Major expansions under Christian IV in the early 17th century transformed it, adding ornate wings in the Dutch Renaissance style, a distinctive spire known as the "Blue Tower," and a grand ceremonial hall. The castle featured a large central courtyard and was surrounded by a moat connected to the harbor. Defensive elements like bastions and ramparts, designed to withstand cannon fire, were integrated following the lessons of the Northern Wars. Its appearance was documented by artists such as Willem van de Velde the Elder and in engravings by Johannes Kip.

Royal residence and functions

For over 400 years, it functioned as the principal residence of the House of Oldenburg and the administrative heart of the Danish-Norwegian realm. It housed the royal chambers, the Exchequer, and the supreme court. The castle was the setting for major state events, including coronations, royal weddings, and the signing of treaties like the Peace of Copenhagen. It also served as a prison for prominent figures; for instance, the disgraced former minister Corfitz Ulfeldt and the mystic Anna Sophie Reventlow were held there before her marriage to Frederick IV. The court life centered here involved figures like the astronomer Tycho Brahe, who received patronage from Frederick II.

Destruction and legacy

By the early 18th century, the castle was considered outdated, damp, and architecturally unfashionable. After a devastating fire in 1794 at the first Christiansborg Palace, there was brief regret over the loss of the older structure. King Christian VI ordered its demolition in 1731 to clear the site for a modern Baroque palace designed by architect Elias David Häusser. The demolition symbolized the transition from a fortified medieval kingdom to an modern absolute monarchy. Its historical role is commemorated in the name of the adjacent Castle Square and through numerous historical accounts, including those by Ludvig Holberg.

Excavations and remains

Archaeological investigations, particularly in the early 20th century and during renovations to the present Christiansborg Palace after the 1884 fire, have uncovered extensive foundations and cellars. These excavations, led by institutions like the National Museum of Denmark, revealed walls from Absalon's original fortress and later medieval expansions. Artifacts such as pottery, coins, and weaponry provide insight into daily life. Today, visitors can see these substantial ruins preserved in the underground museum beneath the present parliament building, Folketinget. The ruins are a protected historical site, managed by the Danish Agency for Culture and Palaces.
