The old Church - Gothic Church in the centre of Delft, one of the oldest buildings in the city and the oldest Church in Delft. In 1050 year there was a small stone Church, it was expanded and rebuilt in 1246, the year when the Delft received city status. The Church is built in Gothic style and was consecrated in honor of St. Bartholomew.

In 1325-50 years the Church was completed with a tower height of 75 meters. For its construction had to change the channel of the old canal town, the old bed was filled, and began construction. Instability of soils on the banks of the canal led to the fact that the tower began to tip. The builders tried to correct the situation by moving the tiers of the tower vertically. Leaning tower was popularly nicknamed "Curve Yang. For a long time the townspeople were afraid of her falling, and even there were proposals to demolish it. Now the slope of the tower is about two meters. The turret is fully stabilized, the risk of decline.

The largest bell in the tower weighs 9 tons, it sounds only during the funeral of any of the royals or during a General alarm.

The first stained glass in the Church appeared in the early fifteenth century, but the fire, and then the explosion of a powder magazine, almost destroyed them. The stained glass Windows, which today adorn the interior, designed in the twentieth century. In the Church there are three body.

Here are buried many famous people, including artist Jan Vermeer and Antoni van Leeuwenhoek, the inventor of the microscope.
