It is also known as the Herensingelkerk, given its location on Herensingel in the Noorderkwartier, but is officially called the Onze-Lieve-Vrouw-Hemelvaart en Sint Josephkerk. The church is a national monument, part of the Historical Canon of Leiden and one of the tallest buildings in Leiden. The church is a design by the Van Laan brothers, built in 1925.
