This last week I had my first vacation in a really long time.
My father, my little sister and I went on an organized tour of Portugal. It was an interesting experience, even if I'm still tired.
The thing that stayed with me was the unusual style of street signs and sidewalks.
The street signs in many towns were made with tiles

The sidewalks were made with small white and black sampietrini (or something that seemed sampietrini). The black ones were used to make mosaics (the image isn't really clear since I was on the bus at the time)

They seem to have a huge amount of sites declared World Heritage, we spent all our stay moving from castles to churches. Our guide was really competent and we learned many interesting tidbits about Portugal and its kings.
All in all it has been a really rewarding experience.
