Spectacular models and massive themed landscapes will form the centrepiece of this year’s Great Western Brick Show, where Lego will fill the Steam museum and the next generation of modellers will be inspired by the creations on display.

Many of the attractions expected at the event, which will take place across this weekend, are still being kept under wraps, but it promises to feature a wide range of Lego-themed activities.

Last year traffic was brought to a standstill traffic with reports of two hour queues as people waited to see all the masterpieces created out of tiny plastic bricks. Around 5,000 attended on Saturday and even before the doors opened at 10am on Sunday hundreds were queuing outside.

The event is organised in partnership with the Brickish Association.

Martin Long, the president of the association and co-organiser of the event, said: “This event attracts visitors from all over the UK and our aim is always to inspire children and adult Lego fans to get building themselves.

“With this in mind, the weekend is packed with amazing displays and special activities, to get everyone involved.”

As well as the expected replicas of famous landmarks, the event will also offer its own take on historical and cultural re-enactments.

Martin said: “The Bricks to the Past history group are back with an epic new model of the Scottish Highlands, depicting a battle scene between the redcoats and Jacobites.

“More gigantic displays will include scenes from 1980s action movies such as Predator, Aliens and Robo-Cop as well as from the classic sci-fi novel War of the Worlds.

“We can’t wait to share the stunning creations that our designers have produced for this event – with many models on display for the very first time.

"As always, we can’t give away too much about this year’s models but the show will be full of surprises!”

Among the attractions will be a giant Lego mosaic which visitors can help build over the weekend, a Lego shop and market place and dramatic Lego robot wars tournaments.

Coun Garry Perkins, Swindon Borough Council’s cabinet member responsible for Steam, said: “Celebrating the well-loved building bricks and the great World of Imagination, this show is a fantastic day out for all the family.

“There is so much to see and do. Visitors also get to enjoy the famous GWR locomotives and new 2017 exhibitions at Steam – as the museum celebrates 90 years since No. 6000 King George V was built in Swindon.”

Visitors who are entranced by the displays and are unable to tear themselves away from the museum will be able to replenish their energy levels at both the Brick Cafe and Steam’s Platform One Café, with freshly made hot and cold refreshments.

Doors open for the event between 10am and 5pm on both days, and tickets will be available on the day.

Prices are £10 for children aged three to 15 and for seniors, and £12 for adults.

Family tickets are priced between £30 and £45, and children under three can go for fee.
