Architect historian Dr Jonathan Foyle (pictured) is climbing the Lincoln Cathedral as part of the 15-episode documentary series Climbing Great Buildings.
The episode featuring the Lincoln Cathedral will air on Tuesday, September 7, at 6.30pm on BBC 2 and BBC HD.
The documentary series sees novice climber Foyle scale Britain’s most impressive buildings, revealing their secrets and life over the last millennium.
Foyle climbed 100ft up the cathedral in July for the second episode of the series, due to its long-standing history and fine example of gothic architecture.
While climbing, Foyle encountered the Lincoln Imp among other gargoyles as well as getting a good look at the stained glass window Dean’s Eye.
Lincoln Cathedral was his biggest climbing challenge of the series because the exterior wall of the cathedral’s central tower is 272ft tall.
