The Old Town of Alcúdia is a popular tourist sight in the northern part of Alcúdia. The old town is surrounded by gorgeus walls and towers built in the 14th century which are illuminated beautifully, if you visit the area during the night time. The area inside the walls consists of old buildings and narrow streets with cafes, restaurants and small boutiques selling hand made souveniers and clothes. While walking along these streets you can sense a huge contrast between the old town and the modern tourist resort outside the walls. The area is about 400 meters wide and within the walls there are many smaller attractions for you to explore.
