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:Rosenborg Palace was built in the period 1606-34 as Christian IV’s summerhouse just outside the ramparts of Copenhagen. Christian IV was very fond of the palace and often stayed at the castle when he resided in Copenhagen, and it was here that he died in 1648. After his death, the palace passed to his son King Frederik III, who together with his queen, Sophie Amalie, carried out several types of modernisation.
The last king who used the place as a residence was Frederik IV, and around 1720, Rosenborg was abandoned in favor of Frederiksborg Palace.Through the 1700s, considerable art treasures were collected at Rosenborg Castle, among other things items from the estates of deceased royalty and from Christiansborg after the fire there in 1794.
Soon the idea of a museum arose, and that was realised in 1833, which is The Royal Danish Collection’s official year of establishment.
