Popular architecture: the town offers fine examples of popular architecture, particularly its fountains, such as in the square of the Peixería Vella, with the effigy of a winged reptile, or in Axesta Street, Real Street (known as the Fonte Vella) or the neighbourhood of O Carme. Another interesting feature is the cruceiro or roadside cross that presides over the square of A Rosa or O Cristo.

Fishermen?s cottages and stately homes: these are the city?s most characteristic buildings. They feature walkways covered by pointed or semi-circular archways, which once covered slabs for salting fish. The houses are built on one or two floors, with balconies adorned with forged iron railings supported by large stone pillars. These buildings are interspersed with Gothic and Baroque manor houses (particularly in Real, Peixería Vella and Mariña Streets), together with more recent buildings, some of which are Modernist in style, which include glass galleries that are so typical of the Galician coast. At the point where Axesta Street and Real Street meet, there is an impressive four-storey building that contains the Municipal Market, which includes a monumental twin staircase with a stone balustrade.

The upper part of the historic centre: climbing the slopes of the hill on which the city is built, we arrive at San Pedro de Muros, the old collegiate church of Santa Maria do Campo. It has a beautiful cobbled vestibule with a cruceiro or cross, used in the Middle ages as the town hall and the guild of seafarers. Dating from the fifteenth century, it is a magnificent example of ?Maritime? Gothic, with a single nave, built over a previously-existing Romanesque structure. Visitors should see the Gothic Cristo da Agonía in its interior, as well as the Modernist Rectory that stands nearby, as well as the hermitage of San Roque at the highest point of the city, offering splendid views over the whole area.

At the entrance to the city from Noia is the Sanctuary of A Virxe do Camiño, a monumental fifteenth-century Gothic structure with some Romanesque remains from a previous building. Its interior includes a sculpture of the Virgin Mary, which according to tradition arrived by sea and was washed up on a nearby beach.
