Plaza de Bilbao and Prim street make up a unique urbanistic development, representative of the San Sebastian's tastes during the period when it underwent its first urban expansion. The Plaza de Bilbao, for example, was built between 1900 and 1906. The design is neoclassical in style mostly, but incorporates "eclectic" details as well. Continuing down along Prim street, several buildings are good examples of the varying styles and this eclectic architecture. In particular, the building found at number 10 is a good example of Art Noveau style; number 21 is Neo-baroque and lavishly decorated inside and out; number 7 is a reinterpretation of the Renaissance style; and number 25 is modernist with an outstanding wrought-iron gate.
