Slough – Our Lady Immaculate and St Ethelbert

Wellington Street, Slough, Berkshire

A fine landmark church, its design inspired by the medieval churches of Norfolk. The building has a tall, spacious interior and a number of furnishings of note. The presbytery is almost contemporary and is built of similar materials. However, the setting of the church is marred by the location at the edge of a busy roundabout.

In the early 1880s an Italian priest named Fr Joseph Clemente arrived in Slough as chaplain  to  Baylis  House  School.  As  well  as  serving  its  pupils,  the  chapel  was attended by local Catholics. Fr Clemente and his supporters subsequently raised enough money to buy the freehold of a disused warehouse and stable on Herschel Street, less than half a kilometre south of the present church. These buildings were converted to become the first St Ethelbert’s church in November 1885. In 1888 Fr Clemente gave up his chaplaincy at Baylis House in order to devote himself to St Ethelbert’s.

In 1889 land for the present church on Curzon Street was bought at a cost of £1,050. Fundraising efforts progressed slowly; work on the building did not begin until May 1908, following a donation by the Superior of St Bernard’s Convent in Slough in memory of her parents.

The church was designed by the architect-priest Fr Benedict Williamson, assisted by Fr J. Francis Drake, chaplain of St Bernard’s Convent, who apparently influenced the building’s East Anglian character. Another influence may have been Bentley’s Holy Rood, Watford, also a flint church in the Perpendicular Gothic style, completed ten years earlier. The foundation stone at Slough was laid and blessed on 1 July 1908.

The builders were Messrs. Godson and Sons. The consecration and opening of the church took place on 19 and 20 April 1910.

A  major  scheme  of  repair  and  reordering  by  Anthony  New  of  Seely  and  Paget included the moving of the oak screen to a new position behind the altar (which had already been moved forward to allow for westward celebration), the moving of the font to the sanctuary area where it was balanced by a new ambo, replacing the pulpit.

Today,  Our  Lady  Immaculate  and  St  Ethelbert’s  is  the  main  Catholic  church  in Slough, serving a large multicultural community. Daily Mass is well attended and around 600 people attend Masses at the weekend.

The design is modelled on that of the old parish churches of north Norfolk, and particularly St Nicholas at Wells-next-the-Sea. The church is in the English Perpendicular Gothic style, and is constructed in local stock brick faced with Chiltern flint and Kentish ragstone. Limitations of the site meant that the church was built with a north-south orientation, but this description follows conventional liturgical orientation (i.e. chancel at east end and so on). The plan consists of sanctuary, nave, aisles, Lady Chapel (north of the sanctuary), Passion Chapel (south of the sanctuary), northwest porch and west tower. Adjoining the Passion Chapel is a sacristy which leads to a covered passageway to the presbytery. The total length of the church is 130 ft; the width of the nave and aisles is almost 55 ft. The tower, crowned by a leaded octagonal spirelet, is 24 ft square and 74 ft high. The internal walls of the church are plastered, apart from the Bath stone columns and arches. The window tracery is Portland stone.

The list description (below) makes no mention of the architect and does not describe the furnishings in any detail.

There is a three-bay, 26 ft high carved and part-gilded oak rood screen, originally at the chancel arch and moved further east in 1980. Above, the rood figures of Christ flanked by the Virgin Mary and St John. Beyond this at the back of the sanctuary, below the east window, is a carved timber reredos with canopied niches containing (from left to right) richly polychromatic figures of St Augustine, St Ethelbert, Our Lady, St Laurence and St George.

There are two stone side altars. The side chapels have smaller oak screens, and there are parclose screens between the side chapels and the sanctuary (also in oak).

In front of the rood screen is a stone forward altar, ambo and stone octagonal font with wooden cover. The font was the gift of Mr James Elliman in 1912, and was moved to its current position in 1980, after which the original baptistery was converted into a reconciliation room and occasional shop. The baptistery is described in the list description as located to the northeast (ritual southwest) of the nave, but a plan of 1960 shows that it was at the west end of the north aisle.

The simple wooden pews of the nave are original. The carved timber Stations of the Cross date from 1912. Stained glass in the nave windows depict (working clockwise from the west end) the Annunciation; St Ethelbert; the Millennium of Christianity in Poland; the Baptism of Our Lord; St Henrietta of Compiegne; St Cecilia; Our Lady and St Elizabeth; St Alban, St Thomas of Canterbury and St John Fisher, and Saints Joachim and Anne. The maker/designer of the windows has not been established. The remaining windows, including the clerestory lights, have clear glass. A statue of Christ the Redeemer, blessed by the Pope and originally intended for Westminster Cathedral, stands by the side entrance facing the street. It was acquired in 1912.

The organ gallery under the tower is not original; the organ was originally in a gallery above the Passion Chapel. The belfry is reached by a circular turret stair in the south east corner of the tower.
