After these destructive events, reconstruction of the city was commenced in the original location with a slightly altered layout. A modern octagonal layout as drafted by the architect P.M. Ugartemendia was turned down and eventually M. Gogorza's blueprint was approved, then supervised and implemented by the Ugartemendia. This area, the old town, has a neoclassical, austere and systematic style of architectural construction. Constitution Square was built in 1817 and the town hall (currently a library) between 1828 and 1832. Housing in the old town was built gradually alongside the rest of the area.
