Santiago Cathedral of Bilbao was originally built during the 14th-15th centuries as Bilbao's main parish church, and was only declared cathedral in 1950 when the Roman Catholic Diocese of Bilbao was officially created. Its origins probably date to well before the foundation of the city in 1300, when Bilbao was little more than a small enclave of fishermen.
The church is consecrated in honor of the apostle Saint James the Great (Santiago), by virtue of being a point of transit for the pilgrims that followed the Northern branch of the Way of Saint James.
Architecturally, the present building is a mixture of styles: from the 15th century Gothic of the cloister and the main vault, where of special interest are the cloister and the beautiful portal that gives access Correo street (Puerta del Angel), to the ostentatious Gothic Revival façade and spire.
A curious custom is the addition of stone carvings of local merchants along the buttresses of the main vault.References:
Krickenbeck moated castle is one of the oldest on the lower Rhine. Its history dates back to the year 1104, when the castle was first mentioned. It is unclear why the old castle, which was certainly inhabited by Count Reginar, was abandoned or destroyed. In the mid-13th century the castle was moved to the current location. At the end of the 14th century the new castle belonged to the Counts of Kleve.
Johann Friedrich II of Schesaberg converted the castle into a Baroque mansion between 1708-1721. On September 7, 1902, a fire destroyed the entire mansion. From 1903 to 1904, a three-winged castle was built in the Neo-Renaissance style. Today Krickenbeck is a conference center.
