Every year in September, people and places across the country throw open their doors to celebrate their community and history for Heritage Open Days − and it’s all free. Here are some weird and wonderful highlights to discover on your doorstep

Chalk Tower, Flamborough

Built more than three centuries ago in 1674, few have had chance to venture inside Chalk Tower. Originally constructed as an early lighthouse, with passing ships asked to pay a voluntary tax based on their cargo weight to fund the beacon fires, the venture became short-lived after mariners refused to pay and the builders went bankrupt. The tower came to life again in 1792 when semaphore telegraphy was devised to transmit coded messages using coloured flags. It was also brought into active service during the Second World War. Since 1952 the tower has been Grade II listed and Friends of the Chalk Tower will be welcoming visitors to the ground floor area.

H.M. Prison Hull

Hopefully the closest you’ll ever come to staying at his majesty’s pleasure, the Behind These Walls exhibition hosted within H.M. Prison Hull, is a rare insight into the last 150 years of the prison − which opened in 1870 − and other custodial establishments across the city. One such story is that of Ethel Major, the last person and only woman to be executed at Hull in 1934, convicted of the murder of her husband. Brought to life through rarely seen photos and other artefacts, this is a fabulous opportunity to take a peak behind its infamous walls. For security reasons, entry is restricted to the exhibition only.

Designed in 1904 by the famous architect Temple Lushington Moore, the church tower’s 80 step climb will not only reward you with far reaching views from one of the highest vantage points in Harrogate, but for those with energy to spare, there is also the opportunity to have a go at ringing its bells.

Free Admission to Shibden Hall
