The story that haunts this land
Your quest begins on Bruges' Grand-Place, the Markt, where 27 guild houses from the 15th-18th centuries bear witness to the city's medieval commercial power. The Belfry (Belfort), built between 1240 and 1446, rises 83 meters high, and its 366 steps offer a view of a city designated a UNESCO World Heritage site in 2000. Here, the statue of Pierre de Coninck, hero of the Battle of the Golden Spurs in 1302, recalls Flemish pride. You must find the first clue hidden near these monuments that saw Bruges become a major economic force in Flanders.
Next, head to the Burg, Bruges' ancient political center since the 10th century, where the first comital castle stood around 850. The Basilica of the Holy Blood, built between 1134 and 1157, is your next crucial stop. It was here that Thierry d'Alsace deposited the relic of the Holy Blood in 1150, making this place a revered pilgrimage site. The City Hall, completed in 1421 in the Bruges Gothic style, dominates the square with its 65-meter height. You will need to decipher a coded message in the architecture of these buildings to understand the significance of the relic throughout Bruges' history.
The route leads you to the Onze-Lieve-Vrouwekerk, Our Lady's Church, built primarily between 1220 and 1400. Its western tower, 115.6 meters high, is the second tallest in Belgium. This monument houses the tombs of Mary of Burgundy, who died in 1482, and Charles the Bold, Duke of Burgundy, transferred here in 1563. These prominent figures of the Burgundian dynasty left their mark on Bruges' history. Your investigation prompts you to examine the symbols of power and faith carved in stone, revealing forgotten secrets related to the relic and Flanders' influence.
Continue your investigation at Sint-Janshospitaal, St. John's Hospital, founded in 1188. It is one of Europe's oldest, operating until 1977. The Gothic buildings, including a 24-bed infirmary dating from the 13th century, now house the Memling Museum, exhibiting six works by Hans Memling created between 1480 and 1494. This place of care and art, where charity and devotion converge, offers a glimpse into medieval Bruges life. You will need to find a clue among the artworks or hospital relics, seeking to unravel a centuries-old conspiracy.
Your quest concludes at the Ezelpoort, the Donkey Gate, built in 1363. It is the last of the four medieval city gates still preserved, with its 8-meter high arch. Located on the canal and the Dampoort, it is a remnant of Bruges' fortifications from 1297-1360. By passing through this historic gate, you will have followed in the footsteps of Thierry d'Alsace, protected the relic of the Holy Blood, and untangled the threads of a conspiracy that has spanned centuries of Flanders. From this interactive tour, you will gain a deep understanding of the history of Bruges, a historic medieval city and chocolate capital, and its role as the site of the Holy Blood.
