Heilig-Geist-Kirche, Catholic parish church in Lehndorf, Brunswick, Germany

Heilig-Geist-Kirche is the Catholic parish church of Braunschweig-Lehndorf, built in 1952 to a design by architect Fritz Hauk. Its white gabled facade has a large circular tracery window above a pointed-arch doorway framed in grey stone, and a lower tiled-roof section with a row of windows adjoins it. A separate white cylindrical tower with many small round openings was added in 1962.

The Catholic parish of Lehndorf, founded around 1942 as the St. Godehard vicariate, initially held Mass in private homes and in the Protestant Kreuzkirche. The Heilig-Geist-Kirche was built in 1952 to designs by architect Fritz Hauk, with stained glass by Dominikus Böhm, and was consecrated on 14 December 1952 by Bishop Joseph Godehard Machens. The separate tower followed in 1962.

The parish, raised to independent status on 1 April 1963, has since 1 November 2006 also included St. Gereon in Vechelde and St. Elisabeth in Wendeburg. The windows by Dominikus Böhm depict the Holy Spirit's attributes of fire, water and wind as flames, fish, waves, clouds, birds and rays; on sunny Sundays around ten they glow warmly.

The church is typically open to visitors during services and at designated times throughout the week. It is helpful to check current opening hours before planning a visit, as times may change seasonally.

The tower, added only in 1962, has a truncated cylindrical shape meant to suggest a wounded tree of life, stripped of its crown by sin but sprouting new buds through God's spirit. Inside it hang three bells cast around 1750 by Silesian itinerant founders and once rung in Gleiwitz's All Saints' Church.
