The town expanded significantly after Napoleon I chose the site as the new préfecture of the Vendée on 25 May 1804 to replace Fontenay-le-Comte (then under its revolutionary name of Fontenay-le-Peuple). At the time, most of La Roche had been eradicated in the War in the Vendée (1793–96); the renamed Napoléonville was laid out and a fresh population of soldiers and civil servants was brought in. Napoléonville was designed to accommodate 15,000 people. The Hôtel de Ville (town hall) was established on the southwestern side of Place Napoléon in 1814. The town was called successively: • La Roche-sur-Yon (during the Ancien Régime and the French First Republic) • Napoléon-sur-Yon (during the First French Empire) • Bourbon-Vendée (during the French Restoration) • Napoléon-Vendée (during the French Second Empire)

The river Yon flows southward through the commune and crosses the town. • Illustration — The Hôtel de Ville (town hall) of 1814
