Luzernertor, Sempach

Lucerne Gate, Sempach
The Lucerne Gate is the southern entrance to the city.
The construction history of the Lucerne Gate is largely unknown. However, it can be assumed that the tower-like gate was not part of the original city fortifications. Originally (13th century), the gate was probably made of blocks and was around 7.5 meters high, on which the middle tower was later built. It was divided into ceilings, accessed via stairs and had a pent roof. The latter was replaced by a pyramid roof in the first half of the 17th century. And even later, in the late 18th century and early 20th century, the wall that closes off the tower on the north side was installed and the facade was painted.

The construction history of the Lucerne Gate remains largely obscure. However, it can be assumed that the tower-like gate was not part of the original city fortifications. Originally (13th century), the gate was probably constructed from ashlars and approximately 7.5 meters high, upon which the central tower was later built. It was divided by ceilings, accessed via stairs, and had a pent roof. The latter was replaced by a pyramid roof in the first half of the 17th century. Even later, in the late 18th and early 20th centuries, the wall enclosing the tower on the north side was added, along with the facade paintings.Source: sempach.ch/sehenswuerdigkeiten/10900

The old town of Sempach still has two old city gates, although this is the more striking one.
