Church of Santa Maria de Arbas is a good example of late León romanesque, built during the 12th and 13th centuries. It once belonged to the regular order of Saint Agustin. The church has three naves and four pillars supporting the round arches that separate the naves.
It was officially founded in the 12th century by the Count Fruela, El Cid's brother in law.It was ruled as a Colegiata (Collegiate Church) and a Hospedería (Hostelry) by the Augustine monks.As a result of its decline, it became a simple parish church. It was restored after the Civil War. The building consists of fine grey limestone blocks. The gothic chapel was added later, in the 12th century. The sacristy, the tower, the portico and the vaulting of the main nave date from the 17th century.
References:Střekov Castle (Schreckenstein) is perched atop a cliff above the River Elbe, near the city of Ústí nad Labem. It was built in 1316 for John of Luxembourg, the father of the Holy Roman Emperor Charles IV, to guard an important trade route to Germany. After changing hands several times, the castle was acquired by the Lobkowicz family in 1563. Its strategic importance led to occupations by Imperial Habsburg, Saxon, and Swedish forces during the Thirty Years' War, as well as successive sieges by Austrian and Prussian armies during the Seven Years' War.
Although Střekov Castle was heavily damaged during those conflicts and abandoned as a military installation by the end of the 18th century, the 1800s saw many poets and artists visiting the castle, drawn by a new trend of interest in romantic ruins.
