Jalance Castle is a Muslim-origin fortress built in the 11th century, with later Christian modifications. It is situated on a hill above the town of Jalance in the Ayora-Cofrentes Valley. Its history is intertwined with the town's, serving as a defense for the lands and people rather than a feudal stronghold. Archaeological excavations have found ceramic remains from the 11th to the 19th century, indicating long-term habitation.
The castle was a battleground during the Carlist Wars in 1836, defended against the attacks of leader Quílez. Floods in 1864 destroyed its orchards and mills and washed away the stone bridge over the Júcar River, which had also happened in 1740. The walls were restored in the 19th century for civil war protection but later fell into disrepair. Today, efforts are being made to consolidate and preserve it.
The castle has a ten-sided polygonal layout, with walls ending in arrow slits and circular corner towers. It consists of two areas: the upper fortified area and the lower area, originally an Islamic albacar, converted into a parade ground by the Christians.
The upper area is accessed by a staircase leading to a corridor connected to various rooms. These include living quarters, ovens, storage areas, a circular silo, and a rectangular cistern.
Jalance Castle is an ideal spot for adventure sports like 'Rugir Pala' or for enjoying cool summer nights illuminated by the light of the Cofrentes nuclear power plant.
The Walls of Constantinople are a series of defensive stone walls that have surrounded and protected the city of Constantinople (today Istanbul) since its founding as the new capital of the Roman Empire by Constantine the Great. With numerous additions and modifications during their history, they were the last great fortification system of antiquity, and one of the most complex and elaborate systems ever built. They were also the largest and strongest fortification in both the ancient and medieval world.
Initially built by Constantine the Great, the walls surrounded the new city on all sides, protecting it against attack from both sea and land. As the city grew, the famous double line of the Theodosian Walls was built in the 5th century. Although the other sections of the walls were less elaborate, they were, when well-manned, almost impregnable for any medieval besieger.
