Ourense's Plaza Mayor is one of the most emblematic spaces in the historic center: It's a porticoed square with a slight incline, making it unique in Galicia. The slope is used to create a very photogenic perspective. Since the Middle Ages, it has been the city's administrative and social center. Markets, public events, and neighborhood meetings were held here. Notable buildings: City Hall: a 19th-century neoclassical building with an elegant façade and balconies. Palaces and noble houses: several properties with heraldic shields and typical Galician galleries.

It spans the Miño River, linking the historic center of Ourense with the A Ponte neighborhood. It was built in the 1st century AD as a branch of the Via Nova (Via XVIII), connecting Bracara Augusta (Braga) with Asturica Augusta (Astorga). Only traces of the original Roman phase remain, such as rusticated stonework at the ends near the banks. It suffered damage during the Middle Ages; in 1228, under Bishop Lorenzo and with the support of Ferdinand III, it was rebuilt with pointed arches and renovated approaches. Until the 17th century, the bridge repeatedly collapsed. The final work was directed by Melchor de Velasco Agüero around 1660, establishing its current appearance.

Located at the entrance to Triacastela, this wooden sculpture depicts a classic pilgrim with a staff, cloak, and hat. It's one of the most photographed spots on the Camino as it passes through this town. A work of local craftsmanship, it pays homage to the thousands of pilgrims who have passed through this historic Galician village, which was one of the first documented stops on the Camino de Santiago route. A good excuse to stop, stretch your legs, and take a symbolic photo before entering the town. From here, decide whether to continue along the San Xil route (shorter and more mountainous) or the Samos route (longer and with a monastery). Both routes are beautiful, but very different.

Contrary to what the name suggests, this was not the king's palace or residence. It's a lovely little place and good for a break.

The Roman bridge in Ourense, known as Ponte Vella or Puente Mayor, over the Miño River, was built in the 1st century AD as part of a branch of the Via Nova (Eighteenth Century). According to tradition, it dates back to the time of Trajan, although its construction characteristics place it close to the time of Augustus. Of that first bridge, only a few cushioned ashlars from the bases remain, as silent witnesses of the past.

Romanesque church dating from the last third of the 12th century with later alterations. Only the main entrance and part of the façade remain of the original design. It has a Latin cross plan with a rectangular nave, two side chapels, and a pentagonal presbytery. The walls are made of masonry and granite ashlars, and the roof is covered with two- and four-sided tiles. The entrance is Romanesque and features a rounded arch with two archivolts, coved arches, an outer band of truncated spires, and decorated capitals. The tympanum is plain on quoins. The altarpiece in the main chapel is neoclassical.
