The Cathedral Church of Saint Peter and Saint Paul is a cathedral of the Episcopal Church located in Washington, D.C. The Neo-Gothic design was closely modeled on English Gothic style of the late 14th century. It is the sixth-largest cathedral in the world, the second-largest in the United States, and the highest as well as the fourth-tallest structure in Washington, D.C.
The Protestant Episcopal Cathedral Foundation erected the cathedral under a charter passed by the United States Congress in 1893. Construction began in 1907, when the foundation stone was laid in the presence of President Theodore Roosevelt and a crowd of more than 20,000, and ended 83 years later when the 'final finial' was placed in the presence of President George H. W. Bush in 1990. Decorative work, such as carvings and statuary, is ongoing as of 2011. The Foundation is the legal entity of which all institutions on the Cathedral Close are a part; its corporate staff provides services for the institutions to help enable their missions, conducts work of the Foundation itself that is not done by the other entities, and serves as staff for the Board of Trustees.
Most of the building is constructed using a buff-colored Indiana limestone over a traditional masonry core. Structural, load-bearing steel is limited to the roof's trusses (traditionally built of timber); concrete is used significantly in the support structures for bells of the central tower, and the floors in the west towers.
The pulpit was carved out of stones from Canterbury Cathedral in United Kingdom. Glastonbury Abbey provided stone for the bishop's formal seat. The high altar, the Jerusalem Altar, is made from stones quarried at Solomon's Quarry near Jerusalem, reputedly where the stones for Solomon's Temple were quarried. In the floor directly in front of that altar are set ten stones from the Chapel of Moses on Mount Sinai, representing the Ten Commandments as a foundation for the Jerusalem Altar.
References:Celje Castle was once the largest fortification on Slovenian territory. The first fortified building on the site (a Romanesque palace) was built in the first half of the 13th century by the Counts of Heunburg from Carinthia on the stony outcrop on the western side of the ridge where the castle stands. It had five sides, or four plus the southern side, which was a natural defence. The first written records of the castle date back to between 1125 and 1137; it was probably built by Count Gunter. In the western section of the castle, there was a building with several floors. Remains of the walls of this palatium have survived. In the eastern section, there was an enclosed courtyard with large water reservoirs. The eastern wall, which protects the castle from its most exposed side, was around three metres thicker than the rest of the curtain wall. The wall was topped with a parapet and protected walkway.
