Basilica Oudenbosch of the Holy Agatha and Barbara A hidden gem in the Western part of North Brabant. This church is unlike any other church in the Netherlands. Just like the center of Oudenbosch, where the church is located, it’s inspired by Roman architecture. The church and historical center around it are worth the visit. In the Oudenbosch Basilica and the museums surrounding it you’ll discover the special connection that Oudenbosch has with Rome and Vatican city.
