The history of the site of King John's House's gardens can be traced back to the late 1530s when King Henry VIII dissolved the monasteries. Then, King John's House and the surrounding land belonged to the Romsey Benedictine nunnery.

Now, this area has been transformed into a series of beautiful gardens by a group of dedicated volunteers, who have created a welcoming oasis in the middle of town.

Pre-18th-Century plants flourish in the main garden, along with a Victorian terrace and a fountain courtyard.
