This morning walking with the dogs in Plaza España I noticed the changing colored laser lights were on inside the Cultural Center of Telecommunications Museum/ el Centro Cultural de las Telecomunicaciones Museo (CCT) and had to go and check it out.
Looking through the window of the CCT you can see the reflection of the BanReservas and the Casa de Reales behing me. This made for a few interesting images.
