A couple have built a 21ft-long replica of Old London Bridge in their living room out of 400,000 Lego bricks.
Mike Addis, 63, and Catherine Weightman, 58, spent 14 hours a day to complete the construction before Christmas.
It is their 27th massive Lego project, and takes over much of their home in Huntingdon, Cambridgeshire.
They have recreated Old London Bridge of 1400, one of several bridges which spanned the Thames at Southwark, including 78 houses, 500 mini-figures, a castle and chapel.
Features of the 3ft high model include guards patrolling the pay toll of the bridge and bakers and residents.
However, it only includes three quarters of the bridge's entire span, as the full size wouldn't fit in the house.
The model was inspired by the medieval Frost Fairs which were held when the Thames froze over from the 16th century.
The couple took four weeks to make the model after starting in the middle of November, sometimes working 14-hour days to complete it in time.
Economics teacher Addis said: "It's probably our most impractical model because it's right through the centre of the room.
"It splits the room in two - there's a foot gap at one end to get around to the other side of the living room.
"We had a party recently with people on one side of the bridge and some on the other.
"Most people are in awe because it's so big."
They plan to fit themselves and 12 family members - including young children - around the carefully constructed model for Christmas.
"We have the settees on one side but the heaters are on the other side,” said Addis.
"We have separate Lego for the children to play with."
The couple even visited an existing wooden model of the bridge in St Magnus The Martyr Church in London as part of their research to build the Lego replica.
The couple previously built a huge polar bear and a model of Ely Cathedral.
"Everything is individually made, each house is very different,” said Addis.
"Some days we were working 14 hours to get it done.
"You have to be patient. Some of it is quite tricky. To make the curved arches we had to build them with half bricks."
The model will stay up until 6 January.
