The Plaza Nueva of Bilbao is a monumental square of Neoclassical style built in 1821. The square is enclosed by arcaded buildings and accessed by arches known as cuevas (caves).
The main building was the site of the Biscay government, until a new palace was built in 1890. The place is now the site of Euskaltzaindia, the Basque language Royal Academy.
The arches host many traditional taverns and restaurants, some of the most ancient and typical of the city, and some gift and souvenir shops.
Each Sunday, the square provides space for a traditional flea market where ancient books, coins, stamps, birds and flowers are sold. The square is used often for folk demonstrations, festivals and concerts.
References:Herceg Novi was founded (on a former small fishing village, existing since Roman Empire times) as a fortress in 1382 by first Bosnian King Stjepan Tvrtko I and was called Sveti Stefan or Castelnuovo. The Turks conquered Herceg Novi in 1482, and ruled for 200 years, until 1687. However, there was a short pause between 1538 and 1539 when it was held by the Spaniards before they were defeated in the Siege of Castelnuovo. Turkey ruled again until 1687, from then until 1797, the town was ruled by the Venetian Republic.
The Herceg Novi old town is amazing. It is on a fairly steep hill that leads all the way down to the sea. Wandering through the small stairways to the various plazas and fortresses is a many hour adventure.
