VALENCIA'S iconic Prince Felipe Science Museum is 20 years old this year, and is offering free entry tickets to anyone born in the year 2000, when it first opened.
Visitors of any nationality who will turn 20 at any point this year only needs to show their passport or, if they are Spanish citizens, their DNI (National Identity Document) at the ticket office at the entrance on the day they wish to attend.
The offer is valid up to and including New Year's Eve 2020.
Part of the futuristic City of Arts and Sciences (Ciudad de las Artes y las Ciencias), the science museum holds a variety of temporary exhibitions year-round, often interactive.
Previous displays have included genetics, new technology, astronomy and even live experiments.
Since the museum first opened on the complex designed by cult architect Santiago Calatrava, it has welcomed nearly 12 million visitors.
This year, to mark the end of its second decade, the museum is set to open its new Teatro de la Ciencia ('Science Theatre') and the exhibition Play: Science and Music.
