Aula Carolina, School building in Aachen, Germany.

Aula Carolina at the south end of Pontstraße in central Aachen is the former St. Catherine's Church of an Augustinian monastery, now used by the Kaiser-Karls-Gymnasium. The building, first mentioned in the 13th century, was rebuilt after the 1656 city fire, with its foundation stone laid on 11 May 1663 and consecration on 30 July 1687. It has a floor area of 570 m² and was reconstructed in 1980 after World War II damage.

Augustinians from Maastricht took over a dilapidated chapel around 1275 and rebuilt it as their convent church; Charles IV supported the monastery with a donation at his 1351 coronation. After the 1656 city fire the cornerstone of the present church was laid on 11 May 1663, and it was consecrated on 30 July 1687. Secularisation in 1802 ended monastic use, and from 2 December 1805 the church served the school as Aula Carolina. Destroyed in the Second World War, it was rebuilt in 1980.

The name Aula Carolina refers to Emperor Charlemagne, whose school uses the hall. Since 1805 it has hosted school ceremonies, and on 1 September each year the Aachen Peace Prize is awarded here. The hall also hosts classical concerts, lectures, theatre and exhibitions.

The building is easily accessible by public transportation and is situated in a central location. Visitors should check ahead about school hours and events, as access may be limited during regular school operations.

The Aula Carolina is the former St. Catherine's church of an Augustinian monastery; the order is still recalled by Aachen's Augustinerbach street, the Augustinergasse and the Augustinerwald wood with its Augustinerweg near Grüne Eiche. Since 1980 the rebuilt hall has hosted the Aachen Peace Prize ceremony every 1 September, the Anti-War Day.
