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:Visby Cathedral (also known as St. Mary’s Church) is the only survived medieval church in Visby. It was originally built for German merchants and inaugurated in 1225. Around the year 1350 the church was enlarged and converted into a basilica. The two-storey magazine was also added then above the nave as a warehouse for merchants.
Following the Reformation, the church was transformed into a parish church for the town of Visby. All other churches were abandoned. Shortly after the Reformation, in 1572, Gotland was made into its own Diocese, and the church designated its cathedral.
There is not much left of the original interior. The font is made of local red marble in the 13th century. The pulpit was made in Lübeck in 1684. There are 400 graves under the church floor.
