Swedish architect, son of the architect Göran Josuae Adelcrantz (1668-1739). Appointed Supervisor of Court Buildings in Stockholm (1741), he remodeled the riding-master's quarters at Ulriksdal as a theatre in the Rococo style (1753). Drawing on Chamber's Designs for Chinese Buildings (1757), he created the charming Chinoiserie pavilion at Drottningholm (1763-69), and designed two more theatres: Drottningholm (1764-66) and the Royal Opera in Stockholm (1777-82). In 1768-74 he built the Adolf-Fredrik Church in Stockholm, much influenced by French Classicism, and remodeled other Stockholm buildings in a Neoclassical style. //
