Casco Viejo is one of the few areas of Panama City where it is possible to just wander aimlessly. Walk the narrow cobblestone streets and discover colourful colonial manions, the Metropolitan Cathedral, beautiful churches, plazas and some of the most significant Spanish architectural landmarks of Panama. The area is probably the most colorful part of Bilbao, including many shops and taverns, several historical churches (San Antón, Santos Juanes, the Cathedral, San Nicolás), a large food retail market ( Mercado de la Ribera ), the public Arriaga Theatre, the seat of the Academy of the Basque Language (Euskaltzaindia), a ball court, and a public library. It is connected to the rest of the city and conurbation by the subway, tramway and buses. Three public elevators also connect Casco Viejo to the neighbourhoods of Begoña and Solokoetxe, which otherwise demand a rather intense uphill walk.
