A full-size replica of a ninth-century wooden log boat will go on display outside y Gaer Museum, Art Gallery & Library in Brecon on Saturday, April 11.

The display marks 100 years since the discovery of the original Llangors log boat, which was found in September 1925 and is now one of the museum’s exhibits.

The early medieval boat was recovered from shallow water at Llangors Lake, near the Crannog – an artificial island thought to have been a royal court – by local pleasure boat owner Thomas Jenkins.

The replica, measuring 4.6 metres (15 feet), was made in 1993 by Channel 4’s Time Team as part of an episode titled The Fortress in the Lake.

During the programme, the team, led by Sir Tony Robinson, carried out a three-day archaeological investigation of the Crannog and the surrounding area.

The boat was carved from a three-and-a-half tonne oak trunk. While power tools were used to speed up the process, the shaping and finishing were carried out using traditional methods, including an axe, adze and scraper.

These tools, along with materials used to maintain the log boat, will also be on display.

The replica is now in the care of Nigel Gervis of Ty Mawr, Llangasty, who hosted the Time Team in Ty Mawr’s outbuilding during filming of the programme.

One of the aims of building the replica was to better understand how the original boat would have been used.

The historical and archaeological evidence suggests the Llangors log boat dates from the same period as the Crannog.

At the end of filming, the replica was launched on the lake, where it was shown to be relatively easy for two people to launch, paddle, steer and beach.

The programme concluded that boats like this would have played an important role in daily life, allowing people living on the Crannog to travel across the lake and fish.

The display has been organised by the Brecknock Society and Museum Friends, working with Ty Mawr Lime, staff at y Gaer and the Llyn Syfaddan (Llangors Lake) History Group.

It will run from 10:30am to 3:30pm and will also include poster displays about the history of Llangors Lake, past and present.

Visitors will also be able to watch clips from the Time Team programme inside the museum’s Brycheiniog Gallery, alongside the original Llangors logboat.
