The Basilica of the Holy Blood, elevated to basilica status in 1923, consists of a lower and upper chapel. The lower chapel, dedicated to Saint Basil, is Romanesque architecture with ribbed vaults and a 12th-century bas-relief of the Baptism of Christ. Via the Ter Steeghere staircase, you reach the upper chapel, where the relic of the Holy Blood is kept. The chapel features 19th-century Neo-Gothic decor. The museum houses valuable artworks, including the Great Shrine by Jan Crabbe (1614).
