You could help choose the winner of the Art of Building photography competition, showcasing the best images of the built environment. Launched in 2010 by the Chartered Institute of Building, the competition is open to both professional and amateur photographers. This year's competition attracted thousands of entries, and the judges have narrowed it down to a shortlist of 12 images. Now it's up to the public to choose the winner of the £3,500 cash prize.

IBTimes UK presents the 12 finalists, including a bell tower that looks like an eye, an atmospheric French theatre, an intricate atrium, and a splash of colour from Brazilian architect Oscar Niemeyer. You can vote for your favourite at the Art of Building website.

This year's competition attracted thousands of entries, with more than 70% coming from outside of the UK. CIOB competition organiser Saul Townsend said: "The breadth of photography we see is amazing. From those who are revealing a little known building to those showcasing a familiar icon in a new light. Best of luck to all our finalists." Public voting is now open on www.artofbuilding.org until 8 January 2018.
