Earlier this week I was in the tourist/town hall office renewing our empadronamiento. This getting your name on the census of people with property or who live locally. Apparently, you are supposed to renew this every 5 years. You should also renew it in between times iof you change your passport.
While there I spotted the machine in the photo above. It allows you to buy tickets for events organised by the council. It should be good for the concerts at the castle in the summer. Plus things taking place at the theatre in El Ejido.
