The city of Lugo is located in Galicia, on the route to Santiago de Compostela. I encountered a few pilgrimage cyclists on the way, but no hikers. Lugo's WHS status is for having the only Roman city walls that are both intact (i.e. authentic enough) and entirely complete. In this, they beat the similar ones in Carcassonne, Avila and Le Mans (according to the ICOMOS evaluation at inscription).
My goal for the day was to walk the entire circuit (2km). I accessed the ramparts from the Rua do Teatro. The most amazing thing, at first sight, is how broad this wall is! Four to seven meters wide apparently. It's just like a major road. The only comparison that directly came to my mind is the City Wall of Xi'an in China (it is newer, 14th century, but even wider). If I remember well, they even allow cyclists there.
It's a very fine stroll. It goes up and down slightly, the heights of the wall very between 8 and 12 m. You also get a good look at the city from all sides, although it's a kind of 'railway view' (in plain sight are not the best of houses). I encountered lots of joggers on my walk, some even twice. For a good exercise one has to round the circuit several times.
The entire walk took me about half an hour including photo stops. A quick site to visit! I didn't venture into the city center of Lugo, but made my way north to other Roman remains instead: theĀ Torre de HerculesĀ in A Coruna.
