While we were recuperating from the flight over, we saw interesting things in Lisbon.
There was the Castello de Sao Joao, dedicated to St. John the Baptist who is extremely popular in Portugal.
You have to climb a lot of steps and slopes to get up there, but the view is great.
The staircase alone was over 100 steps. And then there were sloping lanes! Clearly this castle had an excellent view of the surrounding countryside when it was built.
There were some archeological investigations inside the complex, too. A prehistoric Celtic village and a historical era compound occupied by Muslim administrators (who had stayed over from the previous regime, I think) were excavated and labeled for the visitor to see.
Just imagine doing this stair in a hurry, with armor on!
