St. Catherine's Church in Hoogstraten, Belgium, was built between 1525 and 1550 by order of Antoon van Lalaing and Elisabeth van Culemborg, Count and Countess of the County of Hoogstraten. The imposing building is also referred to as "Cathedral of the Kempen" or popularly as "our Katrien".
The church is built in late Gothic style, more specifically a mixture of Kempen Gothic and Brabantine Gothic, based on plans by architect Rombout II Keldermans (died in 1531). The tower has a square base and is 104.7 meters high, corresponding to approximately 150 Brabant cubits. The base of the bell tower is quadrangular and merges into an octagonal (8 is the number of infinity) candle with flame, a double pear spire covered with slates. The design incorporates white layers of sandstone.
The church is the third tallest church building in Belgium. Characteristic is the red Kempen brick, which while typical of the region, is rarely used for towers of that size. Although it is not the highest brick church in Belgium, it is the church where the brick is the highest.
The church did not suffer in the religious riots of the 16th century, but on October 23, 1944, the tower was dynamited by the retreating German troops just before the liberation. Reconstruction followed from 1952 to 1958.
The church has been a protected monument since 1936.
