A museum visit today.

Holland 1 was the first submarine commissioned by the Royal Navy. She was the first in a five-boat batch of the Holland-class submarine, launched in 1901. She sank 12 years later in 1913 when under tow to be scrapped following her decommissioning. She was recovered in 1982. She was preserved and put on display at the  Royal Navy Submarine Museum, Gosport.
