The river Miño, which crosses the city halfway through its course, has determined the current appearance of the provincial capital. Almost two thousand years ago, the Romans settled in this land attracted, among other reasons, by its thermal springs. The best-preserved legacy of that age is “a ponte vella” (the old bridge), which connects the banks of the Miño and which has grown to be the symbol of the city. This major piece of civil engineering was restored in the 13th and 17th centuries, giving it its current appearance, with a pointed arch and ramps.The capital's rich heritage can be discovered all along the streets which make up the Old City. The arcaded Main Square was the centre of the city's social and trading life, since it was here where markets, festivals and all kinds of cultural and social events were held. The City Hall building dominates the scene. Construction dates from the end of the 19th century. It has classicist façade with a balcony on the first floor and porches on the ground floor, crowned by a coat of arms and a clock at the top.
