Heilig-Kreuz-Kirche, Catholic church in Halle, Germany

Heilig-Kreuz-Kirche is a modern church building with a crystalline structure featuring a low central interior space and a deeply sloping pent roof. Designed by architects Niebergall and Schaller, the building showcases exposed rafters and beams throughout its interior.

The parish of Hl. Kreuz was founded in 1955, after the number of Catholics in Halle rose sharply with the arrival of German refugees and expellees. Its first church, converted from a horse stable by architect Max Kropp, was consecrated on Palm Sunday, 3 April 1966, and became an independent parish that same year. Planning for a new church began in the late 1980s, when new church buildings were politically difficult in the GDR. The old church was demolished in July 1990, the foundation stone laid at the end of 1990, and the new building consecrated on the fourth Sunday of Advent 1991.

Since 1988 the parish has belonged to the Community of the Cross of Nails, a network that began in Coventry and works for reconciliation. The parish is named after Carl Lampert, a Catholic priest executed in Halle's Roter Ochse prison on 13 November 1944 and beatified in 2011; the prison lies within the parish area.

The church stands at Gütchenstraße 21 in Halle's northern district. The interior is oriented by a continuous clerestory running the full length of the roof ridge, between two longitudinal beams, which lights the low central space. The open roof construction leaves the rafters and beams visible above the congregation.

The church is a member of the Nagelkreuzgemeinschaft (Community of the Cross of Nails) since 1988, a link to Coventry Cathedral's reconciliation work. The parish was renamed Carl Lampert on 13 November 2014, honouring the priest executed in Halle's Roter Ochse prison on 13 November 1944.
