Yesterday we went to Montjuic which translates to the mountain of the Jews.  We viewed the famous castle there which was built in the 1600s and was used during the Spanish Civil War as an execution site and military prison.  173 people were executed there during the war.  The view of the harbor and the sea was spectacular - you can see in the middle picture the W hotel in the distance.  We spent the day at the beach there on Wednesday.  The mediterranean was beautiful and the kids really enjoyed playing in the waves.  Below is a video of the castle.
