Bondgate Tower (also known as Hotspur Tower) is a 15th Century stone gatehouse, founded by the Earl of Northumberland, and now privately owned by the Northumberland Estates, which spans the public highway in Alnwick. This tower is of significant historical interest and is a nationally important heritage asset but is now listed on Historic England’s ‘Heritage at Risk Register’, as a result of being classified as being in “very bad condition”. The main cause of this condition is damage to the archway of the tower from being struck by large/high vehicles attempting to pass through the tower and striking the stonework in the process. Further impacts from vehicles on the tower could cause a serious collapse to occur, which would threaten the future of the structure. They could also result in serious injury and/or death, as well as significant disruption to the highway network, and therefore economy, of Alnwick.
