While it may seem a bit early to be celebrating the start of summer, on 20 April the country featured in this image will do exactly that - with an official public holiday, no less.
The reason for this rather strange tradition dates back to the times when the Old Norse calendar, which only divided the year into winter and summer, was observed.
Although the climate in late April cannot be considered anything at all summer-like, after the long winter the nation is keen to celebrate with parades, sporting events and entertainment.
The pictured monument is a cathedral located in the country's capital city. Its unusual architecture and size (it is one of the largest structures in the whole country) make it an emblem of the city.

Congratulations are in order for Adrian Camlett who won last month's competition for correctly identifying the Sint Servaasbrug bridge in the Dutch city of Maastricht, named after the cardinal St Servatius.
Your prize will be with you shortly.
