The Aegidienkirche was a church in Hanover, the capital of Lower Saxony, Germany. It was one of three churches in the Old Town, the others being the Marktkirche and the Kreuzkirche. During the World War II, it was destroyed and left in ruins as a war memorial. The church was built in the 14th century in the centre of Hanover, succeeding a chapel, and a Romanesque church built in 1163. The western wall of that church is partly extant. It was dedicated to Saint Giles, one of the Fourteen Holy Helpers. The present Gothic building was built in 1347 of sandstone from the Deister. The steeple was decorated with a Baroque facade in 1703 to 1711, designed by the German master builder Sudfeld Vick. The interior of the church was remodeled in 1826 by the German architect Georg Ludwig Friedrich Laves who used columns from cast iron. The Aegidienkirche is now part of the Marktkirchen community, to which the previously independent four Hanoverian old town communities - Marktkirchengemeinde, Aegidienkirchengemeinde, Kreuzkirchengemeinde and Schlosskirchengemeinde (until 1943 in the Leineschloss) - joined together.
