Built in the Brabantine Gothic style and so named for its chapel dedicated to St. Michael and for housing the relics of St. Gudula, this cathedral's current structure dates back to the 11th century and took some 300 years to build. Inside, you will find stained-glass windows, statues, paintings, a new Grenzing organ and a crypt that may contain the remains of St. Gudula with ancient Roman graffiti on it. Below the current church are the remains of a 10th-century Romanesque church. Outside the cathedral is a square where you can sit on benches under the shade of honey locust trees.

Past visitors appreciated the architecture of the church, with some noting the beauty of the stained-glass windows in particular and described it as "amazing" and "stunning."

The St. Michael and St. Gudula Cathedral is located about a half-mile from the Grand-Place and is open daily from around 7 a.m. until 6 p.m. Monday through Friday, from 8 a.m. until 5 p.m. on Saturday and from 1 p.m. until 6 p.m. on Sunday. You can attend services and explore the main parts of the cathedral for free, but if you wish to take a peek at the archeological site, you will have to pay an extra euro. Meanwhile, the crypt is open for viewing by appointment only and costs 3 euros (about $3.25) to access. For more information, visit the church's website.
