The Cathedral of St. Matthew the Apostle in Washington D.C., most commonly known as St. Matthew's Cathedral, is the seat of the Roman Catholic Archdiocese of Washington.
St. Matthew's is dedicated to the Apostle Matthew, who among other things is patron saint of civil servants, having himself been a tax collector. It was established in 1840. Originally located at 15th and H Streets, construction of the current church began in 1893, with the first Mass being celebrated June 2, 1895. Construction continued until 1913 when the church was dedicated. In 1939, it became the cathedral for the newly established Archdiocese of Washington.
The structure is constructed of red brick with sandstone and terra cotta trim in the Romanesque Revival style with Byzantine elements. Designed by architect C. Grant La Farge, it is in the shape of a Latin cross measuring 47 m × 41 m and seats about 1,200 persons. The interior is richly decorated in marble and semiprecious stones, notably a 11 m mosaic of Matthew behind the main altar by Edwin Blashfield. The cathedral is capped by an octagonal dome that extends above the nave and is capped by a cupola and crucifix that brings the total height 61 m.
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.
