A pedestrian bridge connecting the city to the other side of the Sado River, where there is a children's playground and the embarkation/disembarkation port for boats offering river tours. This pedestrian bridge also allows for very pleasant walks along both sides of the river. 👍🥾

It's also very easy to cycle. Some paths along the route toward the nature reserve are fenced off as private property. Therefore, plan time and energy reserves for detours.

The Church of Santiago stands on an imposing platform with a grand staircase. The sober, uncluttered and straight exterior contrasts with the richness of the interior, where the paintings, carvings and tile panels stand out. The temple, consisting of a single large nave, typically from the 18th century, is flanked by the arches of the chapels of Mannerist and Baroque inspiration.

The current Church of Santiago is the successor to the primitive chapel dedicated to the patron saint of the order, originally built inside the castle, next to the town hall and the convent. Construction began in the early 18th century.

The author of this highlight probably means EIFFEL and is referring to Gustave Eiffel, who constructed numerous half-timbered bridges in many countries, but achieved world fame primarily as the builder of the Parisian landmark, the Eiffel Tower. The family name is spelled with a double F, in contrast to the low mountain range "Eifel" located in the far west of Germany (where his ancestors came from, however, before the family emigrated to France). If the 1945 date given in @Javier_DD's post is correct as the year of the inauguration of this bridge, it could NOT have been built by Gustave Eiffel, as he died in 1923.
