Tour St-Jacques

Located in Paris' IVe arrondissement, Tour St-Jacques was once part of a church known as Saint-Jacques-la-Boucherie (literally, Saint James the Butcher). It was the patron church of butchers and was frequented by the wealthy wholesale butchers that sold their goods at the nearby Les Halles market. Pilgrims used the church to meet before embarking on their long journeys.

The church was built between 1509 and 1523 and was named for St. James the Great. (A statue of the saint was placed atop the tower in the 19th century.) In 1797, during the French Revolution, the church - like many others - was demolished, leaving only the tower, which is now considered a national historic landmark.

In the mid-1800s, the tower, late Gothic in style, was restored by the architect Théodore Ballu. At that time, it was raised onto a pedestal and a small park was built around it. Putting the tower on a pedestal allowed it to retain its original height despite the absence of the remainder of the church.

The tower was designed in the Flamboyant Gothic style and, indeed, it is quite ornate, full of crockets and plenty of niches that hold a variety of statuary. The tower stands 52 meters high (about 171 feet).

In the mid 17th century, mathematician and physicist Blaise Pascal chose to use Tour St-Jacques as his laboratory, where he conducted a variety of experiments on atmospheric pressure.
number of meteorological instruments were placed on the roof.

There has been much concern about the state of the stone from which Tour St-Jacques is built and the tower has been covered with scaffolding for nearly five years while experts were examining the current conditions. They discovered that most of the stone came from the original structure and was not added when the tower was stored in the 19th century.
