Medieval streets will not leave anyone indifferent. The town is popular for the early Spanish culture.
The main attraction is the monastery of the 13th century. It was founded inside the Arab palace, which was presented to the monks by the king. Don't forget that southern Spain was an Arab territory in those years. Inside there are the museums of Frederic Chopin and George Sand, who rented some of the rooms and spent the winter there. Sand wrote a famous travel novel A Winter in Majorca (https://en.wikipedia.org/wiki/A_Winter_in_Majorca).
Park near the monastery.
Traditional Spanish ceramic plates. They depict scenes from the life of Catalina Thomas, a saint who was born here in 1533.
Even the doors look picturesque. Each street has a huge amount of flowers and greenery.
We spent the night in a beautiful historic Hotel Sa Vall (booking.com). On the next photo it is in the foreground. If you are travelling by car then turn here N 39 42.652 E 2 37.698 and pay attention to the cats who live there and meet each guest. On that spot you also can stop for a few minutes if you want to take such a photo.
Terrace in the hotel.
