Carl Haller von Hallerstein

Johann Carl Christoph Wilhelm Joachim Haller von Hallerstein (10 June 1774, Burg Hilpoltstein, Hiltpoltstein, Principality of Bayreuth – 5 November 1817, Ampelakia, Thessaly, Ottoman Greece) was a German architect, archaeologist and art historian.

He is best known for his role in the 1811–1812 excavations at the Temple of Aphaia on Aegina and the Temple of Apollo Epicurius at Bassae, where he worked alongside Charles Robert Cockerell, John Foster Jr. and others. The group removed the Aphaia pedimental sculptures and the Bassae frieze, which were clandestinely exported and later sold. Modern and contemporary accounts describe the removals as acts of antiquities smuggling and plunder. The Aphaia marbles were acquired by Crown Prince Ludwig of Bavaria for the Glyptothek in Munich, and in 1815 the British Museum purchased the Bassae frieze at a London auction from Haller von Hallerstein and his associates.
