Burg, Medieval square in Brugge, Belgium.

The Burg is a flat, open square of about 1.1 hectares, larger than the Grote Markt, paved in light grey stone and enclosed by historic buildings. On one side stands the Gothic Town Hall with its pointed turrets and steep dark roof; opposite is the former Manor of the Franc of Bruges with tall rectangular windows and a central stone gate. The square remains divided into two adjoining parts, and the Burgstraat connects it to Philipstockstraat.

The Burg began as a walled fortress of about one hectare at the crossing of the Oudenburg-Aardenburg Roman road and the Reie. Count Arnulf I (889–965) expanded it to roughly 1.5 hectares as an administrative centre. From the 11th to the 13th century, Het Steen on the west side housed the counts of Flanders. Saint Donatian's Church became a cathedral in 1559 and was demolished in 1799, doubling the square to about 1.1 hectares.

The name Burg comes from Middle Dutch for "fortress", recalling the walled stronghold that once stood here. The square is still split into a southern civil half and a northern religious half, a division dating from the castle church and chapter of canons. The former Manor of the Franc of Bruges, the City Hall and the Basilica of the Holy Blood line its edges.

The Burg is a flat, open square of about 1.1 hectares, divided into two adjoining parts; the Burgstraat connects it to Philipstockstraat. The square is paved and largely empty, so orientation is easy. Parts of the foundations of Saint Donatian's Cathedral, demolished in 1799, can be seen in the cellars of the Crowne Plaza Hotel.

In the night of 13 to 14 February 1967, a bomb exploded at the gate of the courthouse on the Burg. No one was killed, but the stained-glass windows of the city hall, the courthouse and the Basilica of the Holy Blood were completely destroyed. Despite dozens of house searches and interrogations, the case was never solved.
