Well worth the detour we took from a nearby place we were staying at. The town is very pleasant. We parked at a large municipal free parking lot and made our way into the old part of town that was once home to the romans and is surrounded by walls from the medieval period. The squares in the town are large and dotted with restaurants. We walked up some streets until we came upon the ruins of this roman temple located next to a medieval church with stunning architecture. However, it was the temple that caught my imagination and wonder. As you look upon the ruin you cant help be be in awe of the skill of the builders and how they managed to move such large stones into place. And yet here it still stands many centuries later. There is a small park in front of the Temple and if you stroll to the walled edge of the park you can see a wonderful view of the town and surrounding areas. What caught my eye was the roman aqueduct that still stands there to this day almost in tact as it was when first built. The was how the cleaver Roans moved water from a source to the city itself. An amazing form of engineering and architecture. Its worth a detour from the A6 highway of your travelling on it to or from Lisbon.
