De Vere Horsley Estate Launches Immersive Tunnel Experience Following Reopening of Historic Hidden Passage

De Vere Horsley Estate has unveiled a new immersive heritage experience following the reopening of its historic secret tunnel, which has remained closed to the public for more than 50 years.

The new ‘Horsley Tunnel Experience History Tour’ combines storytelling, food and drink pairings and live heritage interpretation to create a multi-sensory experience centred around the estate’s rich history and its connection to pioneering mathematician Ada Lovelace.

Located beneath Horsley Towers, the tunnel originally operated as a discreet underground route used by servants and tradespeople during the 19th century. Closed since the 1970s, the passage has now been restored and incorporated into a new experiential offering designed for corporate groups, meetings, private events and celebrations.

The immersive tour guides guests through key periods in the estate’s history, introducing figures including William King, Ada Byron and Sir Charles Barry, whose influence helped shape the architecture and identity of the estate during the Victorian era.

Designed to blend heritage with hospitality, the experience includes themed food and drink pairings inspired by different historical periods and personalities connected to the venue.

Priced from £24 per person, the experience has been created as an enhancement for conferences, meetings and private events, giving organisers an additional interactive element that moves beyond traditional drinks receptions or breakout activity.

Kate Shaw, Sales Director at De Vere Horsley Estate, said:

“The reopening of the secret tunnel at De Vere Horsley Estate is a truly special moment, celebrating both the estate’s heritage and its connection to the local community. It brings to life the extraordinary stories of those who lived here, particularly Ada Lovelace, whose legacy continues to inspire.”

Set within 75 acres of Surrey parkland, the estate is located approximately one hour from central London and combines a historic mansion house setting with conference, meetings and accommodation facilities.

Originally redesigned in the 19th century by architect Charles Barry, best known for his work on the Palace of Westminster, the estate remains closely tied to the story of Ada Lovelace, who is widely regarded as one of the world’s first computer programmers.

Alongside its historical significance, the tunnel also holds strong local connections, having previously hosted community celebrations, vintage car events and even featured within the BBC’s 1972 supernatural drama The Stone Tape.

The launch reflects a wider trend towards venues creating more experience-led event offerings, particularly within the meetings and corporate hospitality market, where organisers are increasingly looking for interactive and location-specific experiences that extend beyond the meeting room itself.
