The story that haunts this land

Your quest begins at the Drents Museum in Assen, founded in 1854 as the provincial museum of Drenthe. The neo-Renaissance building, erected in 1907 by D.A. Benjamins, houses a permanent collection of 85,000 objects. This is where major discoveries are preserved, such as the bog bodies from Drouwenerzand, dating back to 530 BC, silent witnesses to ancient civilizations of the Drenthe peat bogs. Your first puzzle plunges you into these vestiges, searching for a clue hidden among the archaeological artifacts of the Netherlands.

Continue to the Abdijkerk, a church built between 1224 and 1250, part of the Cistercian monastery Mariënkamp. The 50-meter-high tower, rebuilt after a fire in 1791, and the 16th-century stained-glass windows, restored in 1950, tell the religious history of the province. Used as a parish church since 1600 after its secularization, it is a key Dutch National Monument. Here, you decipher a message hidden in the Gothic architecture, linked to the monks' influence on Drenthe's cultural heritage.

The route then takes you to the Brink, Assen's historic central square since the 13th century. A weekly market has been attested here since 1258 by a charter from the Count of Drenthe. This 12,000 m² square, surrounded by 36 listed Rijksmonumenten buildings, was a site of public execution until 1853. The Hof van Coevorden, an old comital palace rebuilt in 1551 and linked to the Battle of Anloo in 1227, stands nearby, its Dutch Renaissance gabled facade bearing witness to the establishment of provincial government. It is in this square that you must reconstruct an ancient proclamation, essential to your mission.

On your way to the Provinciehuis Drenthe, you cross the Wilhelminapark, created in 1897 for Queen Wilhelmina's jubilee. This 3.2-hectare park, with its 250 century-old trees and 1900 neo-classical pavilion, is a witness to Assen's urbanization at the end of the 19th century. The Provinciehuis itself, built in 1887-1888 by J.A. Beltman, has been the seat of the provincial government since 1888. Restored in 2005, it preserves its historic facade while incorporating modern innovations. A puzzle awaits you in its gardens, connecting nature to the governance of Drenthe.

Your exploration of Assen concludes at the Koepelkerk, built in 1882-1883 in a Neo-Romanesque style by A. Anastasius. Its central dome, 18 meters in diameter, and its 45-meter tower, listed as a monument in 1971, make it a Reformed edifice capable of accommodating 1,200 people. This thematic walking tour will have allowed you to grasp the history of Assen, from its medieval roots to its urban development. As Willem Lodewijk, you will have unlocked the "Shadows of the Bog," revealing the deep connections between Drenthe's heritage, its Rijksmonumenten, and the buried tales of its peat bogs. Your interactive visit to Assen concludes, the mysteries of the past forever etched in your memory.
