Aegidienkirche Heilbad Heiligenstadt, Parish church in Heilbad Heiligenstadt, Germany.

Aegidienkirche is a parish church with Gothic-style features, tall windows, and ornate altar furnishings set within thick stone walls. The interior appears bright and spacious, with arched ceilings and religious furnishings from different time periods.

The Neustadt settlement south of the old town grew from 1223 to 1227, and its church of St. Aegidien was first built as a timber-framed structure. That building burned in 1333; the sandstone replacement was completed by 1370, initially without towers. The two towers shown on the 1655 town plan were demolished in 1748 because they leaned outward, and the present south tower was rebuilt only in 1851.

Locals call St. Aegidien the Neustädter Kirche, after the Neustadt district founded south of the old town between 1223 and 1227. The church keeps the relics of the Mainz bishop Aureus and his deacon Justinus, venerated as the town's patron saints, in the celebration altar since they were moved here after 1800. The baroque high altar, built 1689–1691, stood in Quedlinburg's St. Servatius until that parish was expelled in 1938 and reached this church in 1944.

You can enter through the main door on weekdays, and guided tours of the interior can be arranged in advance. Check ahead to find out if services or events are scheduled, as these may affect visiting hours.

The church displays building elements from several centuries, with different styles clearly visible in its walls. These visible layers show how churches grew and changed gradually rather than being completed all at once.
