The Snijderskoor houses the Second Mayor's Window. A stained-glass window was installed for each mayor the city knew between 1760 and 1792. Together with the First Mayor's Window in the Buitenlandvaarderskoor, these windows form a bricked-in record of the city. They offer a unique insight into the history of Amsterdam's city administration from the Alteration in 1578 to the end of the 18th century.

A visual timeline of the city administration
In 1761, M.E was commissioned to produce the Second Mayor's Window, as a sequel to the First Mayor's Window. The upper part of the window is a copy of the first window, which was made by Pieter Jansz. It shows two armoured soldiers. One of them holds a banner with the city coat of arms, while the other carries a staff from which hangs a so-called freedom hat. The soldiers are leaning on two coats of arms: on the left, the old coat of arms of Amsterdam with the bullet ship, and on the right, the new coat of arms with the three crosses.
The rest of the window forms, as it were, a visual timeline of Amsterdam's city government between 1760 and 1792. In chronological order, the glass panes show the coats of arms of Amsterdam's mayors, with inscriptions stating their names and the year they first became mayor. The last two rows of arms represent aldermen of the Batavian Republic. The first set of glass plates was still made by M.E de Angelis, while the later coats of arms were added later.
A select group with power in their hands
Amsterdam was governed until 1816 by four mayors, one of whom served as "reigning mayor". They held supreme power in the city and determined policy at the economic, legal and municipal levels. Most mayors of the time held the office several times and remained influential even as former mayors on an advisory board. Their experience was used to support incumbent mayors in important decision-making.
Besides forming a timeline of the city government, the mayor's windows also show its oligarchic nature. A series of family coats of arms recurs repeatedly on the window for two and a half centuries, showing that power was in the hands of a very select group of influential families. They managed to keep administrative power within their own circles.

Stained glass windows in the Oude Kerk
Stained glass is a form of glass art. In the Middle Ages, the windows of churches were completely or partially stained glass which was held together in lead strips. As a result, light entered the church space in all sorts of sparkling colors. At its peak, the Oude Kerk had 25 stained glass windows, most of which date from the sixteenth century. Maria’s Deathbed was restored in 2025 after a five-year restoration period.
