But ... if you order tickets online, make also sure that the visit to the palace is early, as we arrived at 10am and could only view the palace at 6pm, it was June, parking was easy, almost no visitors (contrary to the summer time).

The photo´s where we sit and have a drink, that is opposite the Alhambra, we took a bus from Alhambra through town, to the hill with the church, which was 2 Euros, we had lunch, but Peter and his wife had late Dinner there in one of the many small restaurants with a beautiful night view at the Alhambra. Food is good in all restaurants, especially the couscous.

The Alhambra (Arabic: the complete name is "Qal'at al-Hambra", which means "The red fortress") is a palace and fortress complex of the Moorish rulers of Granada in southern Spain (known as Al-Andalus when the fortress was constructed), occupying a hilly terrace on the southeastern border of the city of Granada.

Once the residence of the Muslim rulers of Granada and their court, the Alhambra is now one of Spain's major tourist attractions exhibiting the country's most famous Islamic architecture, together with Christian 16th century and later interventions in buildings and gardens that marked its image as it can be seen today. Within the Alhambra, the Palace of Charles V was erected by Charles V, Holy Roman Emperor in 1527.
