Inspired by the recent Brick City exhibition at Guernsey Museum at Candie, the challenge received 26 entries, which were displayed within the museum.
Jo Dowding, access and learning manager at Guernsey Museum, said: ‘It’s not a competition – it’s more of a challenge where all participants receive a prize.
‘I’m overwhelmed by the response we’ve had – this is the first time we’ve done this.’
Participants gathered in the museum on Wednesday, where prizes were handed out.
Eight-year-old Charles Thornton, who built a bird’s eye view of Castle Cornet, said: ‘It was really fun – I made it by myself.’
Ten-year-old Alma Paucar also enjoyed the challenge.
‘It was really fun – I build lots of Lego models at home and I searched lots of things up online to choose what to make.’
Alma recreated the Japanese Pavilion at Saumarez Park.
The Guernsey Cheshire Home also participated in the challenge, creating a model of its premises using donated Lego bricks.
A mixture of the staff, residents and visiting children helped to build the impressive model.
‘Everyone in the home could play a part in making the model – those who couldn’t do the making sorted the Lego into piles,’ said Cheshire Home administrator Karen Le Page.
‘Everybody was so excited – they love doing art projects.’
The challenge was organised in partnership with Island Families, who funded the drinks and cupcakes provided.
