Saint Thomas Church, Lutheran church in Vällingby, Sweden

Saint Thomas Church is a Lutheran church in Vällingby, Stockholm, designed by Peter Celsing and interior architect Ella Öström and consecrated in 1960. Its walls are built of dark-burnt Helsingborg brick, and the nearly square plan surrounds a central courtyard. The church hall lies to the north, while the tower stands at the western end, built of brick and concrete with twenty bells freely exposed. Inside, a wooden crucifix by Bror Hjorth hangs in the church hall.

A church was planned from the start of Vällingby, an early ABC city designed under Sven Markelius, with a plot reserved for Spånga parish. After Backström and Reinius declined the commission, Peter Celsing took it on; planning lasted over six years and construction began only in 1958. The church was consecrated in 1960, and Vällingby became an independent parish in 1974.

The parish belongs to the Church of Sweden and only became independent in 1974, when work on the neighbouring parish house began; that house follows sketches by Peter Celsing and was finished in 1975–77 by Per Ahrbom after Celsing's death. A steel cross stands in front of the church, and the brick walls carry no downpipes or plinth.

The main entrance faces the square on the eastern facade, where a band of windows with black wooden frames sits in the brick wall. The building has an almost square plan around a central courtyard: the church hall occupies the north side, while the sacristy, confirmation rooms and other parish spaces fill the other sides over two floors. A tall steel cross stands in front of the church.

The church walls are laid in dark-burnt Helsingborg brick, chosen so the facades would have no plinth or eaves and stay free of downpipes. On Celsing's suggestion, apprentice masons did the bricklaying to cut costs, and their less regular work gives the walls their uneven surface.
