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:Rosenborg Palace was built in the period 1606-34 as Christian IV’s summerhouse just outside the ramparts of Copenhagen. Christian IV was very fond of the palace and often stayed at the castle when he resided in Copenhagen, and it was here that he died in 1648. After his death, the palace passed to his son King Frederik III, who together with his queen, Sophie Amalie, carried out several types of modernisation.
The last king who used the place as a residence was Frederik IV, and around 1720, Rosenborg was abandoned in favor of Frederiksborg Palace.Through the 1700s, considerable art treasures were collected at Rosenborg Castle, among other things items from the estates of deceased royalty and from Christiansborg after the fire there in 1794.
Soon the idea of a museum arose, and that was realised in 1833, which is The Royal Danish Collection’s official year of establishment.
