15 Best Things to Do in Chichester (West Sussex, England
"In the southwest corner of Chichester’s wall circuit is a charming garden, looked after by Chichester District Council but not in the register or parks and gardens. You can get in via the Bishop’s Palace Cannon Gate on Canon Lane to be dazzled by immaculate formal flowerbeds against the evocative backdrop of the old walls. The arboretum has some 100 exotic and rare trees, while there’s an Alpine garden, a wildlife garden and a rose pergola entwined with clematis, honeysuckle and climbing roses."
