So why is a church called Saint Nicholas known as the Old Church? Because Amsterdam grew fast. In 1334 the town became an independent parish with its own priest, and this church became its parish church. In 1409 a second great church, the Nieuwe Kerk, rose on the Dam. From then on, people spoke more and more of the Oude Kerk, the old one, and the name stuck. Inside, music mattered. From 1468 until 1578, a college of paid, professional singers was attached to the church. Then came the great upheaval. A drawing of the Beeldenstorm of 1566, the wave of image-breaking, survives in the city archives. In 1578 came the Alteratie, the Reformation in Amsterdam. Following William the Silent's defeat of the Spanish in the Dutch Revolt, the church passed from the Catholic Church to the Calvinist Dutch Reformed Church. Its patron saint and its old role changed, but the building and its place in city life carried on. It also stayed a very public space. The church was a meeting place for merchants, and plays were performed here. In this city, trade and faith have always sat close together.
