The Cathedral is constructed of brick which has been covered with lime render and painted ochre to resemble the colour of the original building. The gable roof is covered with shingles. The north and south facades are punctuated by arched windows. Buttresses have been placed at regular intervals down the length of these facades. The portico, which was removed in 1881, has been reconstructed at the western end of the building. The western gable end is punctuated by four arched windows, a pair above the portico and a single window either side of the portico. A lean-to extension is located at the eastern end of the southern facade. Entry to this section is through an arched door on the north facade. The church windows have clear glass set in wooden mullions. Those in the lean-to section are square, four paned windows.
History
The Pro-Cathedral of St John the Evangelist is an important building for the history of the Catholic Church in Western Australia. It was the first Catholic Church and would become the first Cathedral. It was the centre of Catholic life for the first twenty years of the Catholic Church in the Swan River Colony until the first St Mary’s Cathedral was completed in 1865. In 1843 approval for the request was granted from Rome and Father John Brady, Father John Joostens and Patrick O'Reilly were soon to arrive in Fremantle on the ship 'Water Witch'. Even though Father Brady was to stay in Perth for only a short time he was able to claim a land grant for the church, on Victoria Avenue. This was to be the site of the first Catholic Cathedral, the Church of St John the Apostle and Evangelist. Construction commenced on 27 December 1843, with the foundation stone laid on 16 January 1844. In 1844 Brady left for Rome to ask for assistance and advocate the establishment of a new diocese for the Swan River Colony. Following Bishop Brady's arrival back in Perth in January, 1846, the Church of St John the Apostle and Evangelist became a cathedral as it was now the seat of a bishop. The chair that Bishop Brady brought from Europe still remains in the Pro-Cathedral. Bishop Brady left Perth in 1852, following disputes with the Apostolic Administrator, Joseph Serra. In 1850, Bishop Serra replaced Brady as Bishop of Perth and in 1855 he extended the building in brick to twice its original size. The church was rededicated as the Immaculate Conception. In 1856, a brick portico was added to the western side of the building. St. John's Pro Cathedral was the principal place of worship for the Roman Catholic Community in Perth from 1844 until 1865. Upon its completion in 1865 the Gothic-style St Mary's Cathedral replaced St John's as Perth's Catholic Cathedral. The church then became known as St. John's Pro Cathedral and was used by the Christian Brothers as a school. In 1881, St. John's Pro Cathedral was renovated and used by the Sisters of Mercy, under the name of St. John's Chapel, as the school chapel for Mercedes College. In 1965 the building was 'modernised' and used as a classroom for convent students and for external students studying English. Between 1979 and 1980, work was undertaken to restore the building and remove the additions and alterations, which were unsympathetic to the original design. The buildings were then adapted for use as a museum by the Catholic Church.
