S:t Tomas kyrka

S:t Tomas kyrka was built as the parish church for Vällingby, a planned 1950s suburb of Stockholm that was an early example of an "ABC" development combining work, housing and centre. Although a church had been part of the plans from the outset, the commission passed through several hands before being given to Peter Celsing, following the withdrawal of the original architects Backström and Reinius. The design process took more than six years, as Celsing worked closely with the parish to reconcile practical requirements with his architectural vision. Construction finally began in 1958.

The church is built almost entirely of dark-fired brick, with facades notably free of guttering, eaves or other visible fittings, giving the walls a stark, unbroken character. Unusually, the bricklaying was carried out by apprentice bricklayers on Celsing's own suggestion, both to control costs and to produce a more irregular, textured surface than skilled masons might have achieved. The building is arranged around a near-square plan with a central courtyard, recalling a cloister, and the tall steel cross standing before the entrance has become one of its most recognisable features.

Inside, the same dark brick continues on the walls, combined with concrete beams and pale concrete elements in the ceiling and square ceramic tiles on the floor. A tall, narrow window lights the area near the chancel. The wooden crucifix by Bror Hjorth remains one of the most distinctive furnishings, giving the otherwise austere interior a striking focal point.

The church tower, built in brick and concrete, carries twenty bells openly exposed to view, eighteen of which form a carillon, with the remaining two serving as the church bells proper. Vällingby did not become an independent parish until 1974, considerably later than the church itself, and the adjoining parish house was completed only after Celsing's death, based on his sketches and finished by the architect Per Ahrbom in the later 1970s.

The building is considered one of the foremost examples of the churches erected in Stockholm's new post-war suburbs, and it has been given the city museum's highest classification for buildings of exceptional cultural-historical value.
