These 14 acres of beautifully landscaped gardens were originally part of Tonbridge Castle’s grounds and it is still possible today to see much evidence of the Motte and Bailey’s existence. Of particular interest is the remains of the fosse or ditch that was built along three sides (the river protected the fourth side) of the site in 1259 to secure the town from invaders. The importance of this ditch is clear from the number of local roads that contain the word fosse in their name.
