Today, on January 25, Wales commemorates the patron saint of friendship and love, Dwynwen.
According to legend, she was the prettiest of Welsh king Brychan Brycheiniog's 24 daughters. She was unable to marry the man she loved, so instead devoted her life to the happiness of other lovers.
She lived in the 5th century, and built a church on Llandwyn Island, off the coast of Anglesey. Remains of the church - along with Dwynwen's well - are popular for visitors up to the present day.
For many people here, St Dwynwen's Day is now an early - and particularly Welsh - version of Valentine's Day.
