In 1863, the defensive walls of the town were demolished (their remains are visible in the underground car-park at the Boulevard) and an expansion of the town began in an attempt to escape the military function it had held before. Works were appointed to Jose Goicoa and Ramon Cortazar, who modeled the new city according to an orthogonal shape much in an neoclassical Parisian style, and the former designed elegant buildings, like the Miramar Palace, or the Concha Promenade. The city was chosen by the Spanish monarchy to spend the summer following the French example of the near Biarritz. Subsequently the Spanish nobility and the diplomatic corps opened residences in the summer capital. As the “wave baths” at La Concha conflicted with shipbuilding activity, shipyards relocated to Pasaia, a near bay formerly part of San Sebastián.
