During Semana Santa, you can see pre-Easter processions where religious icons and statues are carried through the streets. The biggest processions take place in Las Palmas, the capital of Gran Canaria, but most towns and villages have their own celebrations and processions.
A part of the ceremony takes place inside Sant Ana Cathedral but a great part is followed in the street where people can see the signs and symbols of Easter. The pictures below are what I have taken there in March 2016.
