The Romanesque-style Basilica of the Holy Blood curiously has an ornate Gothic upper level. But most visitors flock to this chapel to look at a small vial of blood, which is said to have belonged to none-other than Jesus Christ. Every year on Ascension Day (in May or June), the bishop of Bruges accompanies the holy relic through the city streets in the Procession of the Holy Blood.

Many visitors say that the exterior of the Basilica of the Holy Blood isn't much to look at, but the inside is a different story. One TripAdvisor user says: "It was interesting to see 2 very different styles in one church. The downstairs sanctuary was very simple while upstairs was overwhelmingly gothic, almost too gothic."

Admission to the basilica is free, while a visit to the treasury museum will cost you a small fee of €1.50 EUR (about $2 USD). Hours of operation are short and vary by season, so be sure to call ahead or check with your hotel concierge before visiting. For more information, visit the official website.
