The Torres de Quart is one of the two remaining gates of the old Valencia city wall. It was built between 1441 and 1493 to the site of 11th century Moorish gate.
Over the subsequent centuries, the city of València was not placed under siege. While the walls of the city were in disrepair, the towers continued to be anchor points in the defense of the city. In the 17th century, the tower was also being used as a women's prison, with many inmates being prostitutes. In 1808, during the Battle of Valencia in the Peninsular War, cannonballs and bullets from French troops damaged the gate. The holes were preserved during future restorations as a memory of the occasion.
The gate was declared a national monument in 1931. It has undergone several restorations and now serves as a tourist attraction.
References:Visby Cathedral (also known as St. Mary’s Church) is the only survived medieval church in Visby. It was originally built for German merchants and inaugurated in 1225. Around the year 1350 the church was enlarged and converted into a basilica. The two-storey magazine was also added then above the nave as a warehouse for merchants.
Following the Reformation, the church was transformed into a parish church for the town of Visby. All other churches were abandoned. Shortly after the Reformation, in 1572, Gotland was made into its own Diocese, and the church designated its cathedral.
There is not much left of the original interior. The font is made of local red marble in the 13th century. The pulpit was made in Lübeck in 1684. There are 400 graves under the church floor.
