A secondary school in Glasgow has been named Scotland's best new building, picking up the UK's top architecture prize and a cheque for £25,000.
The college building came out on top
St Aloysius College's Clavius Building was chosen from a short list of four to win the Royal Incorporation of Architects in Scotland (RIAS) contest.
The finalists included an arts centre at the Eastgate Theatre, Peebles.
Maggie's Cancer Centre in Dundee and the Lotte Glob House in Durness, Sutherland, were also on the list.
Last year's prize was won by An Turas, a unique ferry shelter on the island of Tiree.
This year's winner was chosen by RIAS president Gordon Murray, Andy MacMillan (Emeritus Professor, Mackintosh School of Architecture), Malcolm Fraser (Malcolm Fraser Architects) and Hennu Kjisik (Harris-Kjisik Architects).
The Clavius Building incorporates a state-of-the-art mathematics, science and technology block for secondary pupils.
It won the award for its strong urban presence and clever use of a difficult site, which is near Glasgow School of Art.
The Eastgate Theatre in Peebles is a 19th century church which was converted into a new arts centre.
Maggie's Cancer Centre is the first building in Britain designed by internationally-renowned architect Frank Gehry.
The Lotte Glob House was the smallest and the most northerly of the finalists.
The Scottish Executive is to give the prize a cash boost of £15,000, starting next year.

"Scottish architects are celebrated both at home and
internationally, producing work that is both critically and
She added: "Our policy on architecture and our new support for the RIAS award demonstrates our desire to position Scotland as a forward-thinking, ambitious country where our most talented architects design buildings that fit in with the city, town or landscape."
