. . "The Fort de Boncelles is one of twelve forts built as part of the Fortifications of Li\u00E8ge in the late 19th century in Belgium. It was built between 1881 and 1884 according to the plans of General Henri Alexis Brialmont. Contrasting with the French forts built in the same era by Raymond Adolphe S\u00E9r\u00E9 de Rivi\u00E8res, the fort was built exclusively of unreinforced concrete, a new material, rather than masonry. The fort was heavily bombarded by German artillery in the Battle of Li\u00E8ge."@en . . "Fort de Boncelles"@en . .
