The castle was built around 1370 by order of Albert II, Duke of Mecklenburg, to protect the entrance to the bay and the waterway to the former Västervik, today's village of Gamleby at the end of the bay.

The castle was built in 1807, largely of wood. It remained privately owned until 1969, when it became the property of the city. However, it fell into increasing disrepair until it was renovated in 1993, when it was largely destroyed in a fire. A restoration followed and it reopened in 1994. Today, the castle is a popular tourist destination with restaurants, a boat dock, concerts, and exhibitions. It has since been expanded to include a hotel and spa.

The original castle developed into a fortified palace with several wings under John III in the Renaissance. In the 17th century, the architect Nicodemus Tessin the Elder, commissioned by Charles X Gustav, redesigned the palace into a significant Baroque complex. The previously isolated parts of the building were expanded into four large wings and placed under a shared, imposing roof, with the corner towers capped with dome-like domes. These extensions, however, were not fully completed; the east and south wings were roofed but not expanded. The defensive tower was demolished during the renovation work, and its outline is now embedded in the ground within the palace courtyard.

Borgholm Castle is located near the town of Borgholm on the western side of the Swedish island of Öland. After a fire in the 19th century, it now remains only a ruin, but remains one of Sweden's most important landmarks.
