The 19th century was a prosperous one for Boulogne, which became a bathing resort for wealthy Parisians after the completion of a railway line to the French capital. In the 19th century, the Basilica of Notre-Dame de Boulogne was reconstructed by the priest Benoit Haffreingue, who claimed to have received a call from God to reconstruct the town's ruined basilica. During the Napoleonic Wars, Napoleon amassed La Grande Armée in Boulogne to invade the United Kingdom in 1805. However, his plans were halted by other European matters and the supremacy of the Royal Navy.
