The Castle of Montjuïc crowns the southwest part of the mountain and has some fantastic views over the city and the Mediterranean Sea. Dated back to the end of the seventeenth century, and, in spite of being the site for some of the blackest times in the city’s history, now is a great place to enjoy outdoor cinema during the summer nights or the different activities which they put out throughout the year. Our recommendation is to take the cable car from Barceloneta and go up from there!
