The marvellous picture above is one of three former Admiralty photographs collected by Dennis Laing from Portchester.
They are undated, but he believes they were taken shortly after the Second World War, possibly from the top of the submarine escape training tank at HMS Dolphin.
‘I can’t think of any other building in that area that would have the height,’ he says.
Beyond the submarine in the foreground and the motor torpedo boats moored in Haslar Creek, Gosport stretches out into the distance.
Visible are Haslar drill hall on the left in the mid-disance and beyond that, Gosport swimming pool.
Against the sea wall on the right of the picture are the old water police premises.
I shall print Dennis’s remaining two panoramic photographs in the coming days.
Both were taken from the same place and show Portsmouth Harbour and Old Portsmouth.
