If you are planning on travelling distance to attractions, we would recommend that you contact the venues directly in advance to avoid disappointment.
If you, or any of your party have a new persistant cough, or develop a fever of 38C, we would instead advise you to use the NHS's dedicated website for professional advice.
The museum is an old building of the original HMS Ganges, Stone Frigate which closed in 1976. It was a training establishment for boys of the ages 15-16 years and was closed when the school leaving age rose to 16. There are still boys who trained there serving in the modern navy.
