The Palace of Coudenberg (French: Palais du Coudenberg, Dutch: Coudenbergpaleis) was an impressive complex located in Brussels, Belgium centuries ago. This royal residence situated atop the Koudenberg hill became the seat of power for the counts, dukes, archdukes, kings, and other rulers from the 12th century to the 18th century. For a time it was the center of activity where the DuchessMargaret of Austria formally relinquished her regency over the Low Countries to Charles von Habsburg and Charles V abdicated in favour of his son, King Philip II of Spain. Unfortunately, the palace was destroyed in an accidental fire on the night of 3 February 1731. However, its vestiges and foundations are still visible and open to the public today. Visitors can check out the ruins of the great hall and side chapel, among other features. It's a wonderful way to explore a piece of Belgian history!
