Location
C++ on Sea is hosted at the Leas Cliff Hall in Folkestone in Kent, UK, overlooking the English Channel. This historic seaside town is also home to the channel tunnel and, as such, has excellent links to the rest of europe. It's also very accessible from London with the UK's (currently) only high speed link, the HS1. For more comprehensive travel information, see the page, Getting to C++ on Sea
The Leas Cliff Hall is a working theater that also has a dedicated conference suite. Built into the cliffs, and with floor-to-ceiling glass overlooking the sea on three sides, the views are spectacular!
The venue is about a 15 minute walk from Folkestone Central station, or ten minutes walk to the bustling town centre. As well as the modern town the old quarter, home to art galleries, curio shops and bohemian cafes and restaurants, extends down to the picturesque harbour. It's no wonder The Times voted it one of the best places to live in 2023.
Although the venue is split across three floors, connected via staircases, it is also fully accessible via elevator.
