This is the 1900 Lifeboat Station [?on the site of the 1860 lifeboat house?], refurbished and updated in 1991.
Behind me and to the left, these yellow box markings lead to the lifeboat launching slipway [currently - Oct/Nov 2023 to early 2024 - under reconstruction, so the RNLI are using the slipway by the Harbourmaster's Office - good luck with that, the approach route had got two builder's vans in it at the time I took this image !]
A little to my right behind me and you'll find the RNLI shop.

From 1967 to 2013, the ILB here was "Blue Peter III" ... there were five of these ILBs, and collectively they were used to rescue 277 people.

Since 1860, when the station was first established, three RNLI Gallantry awards and three GOLD Blue Peter Badges have been awarded to crew members.
