Originally founded by King Béla IV in the 13th century, this church is officially named the Church of Our Lady and is a symbol of Buda's Castle District. It is popularly referred to as Matthias Church after the 15th-century king Matthias Corvinus who added a royal oratory and was twice married here. The original church was built in stages that spanned from the 13th to the 15th century. Like other old churches in Budapest it has a history of destruction and reconstruction, always being refashioned in the architectural style in vogue at the time. Renovation has been an ongoing process as financial considerations allow and it is currently half-covered with scaffolding. When I went in to see how long this would continue, I was shocked to hear it was planned until 2012. Regardless, it is a church not to be missed and this one too has Zsolnay ceramic tiles. Do not miss the museum upstairs; often overlooked by travelers who do not realize it is there, it has an interesting history of the royal crown and a wonderful view of the church.
