The first picture is a landmark from Port Elizabeth in South Africa. It's know locally as the 'Tin Hat' as it's shape reminds people of the helmets worn by WWI soldiers. This promenade is at Humewood Beach and stands on the 'Princess Promenade', which was officially opened and Prince and Princess Arthur in 1923. Prince Arthur was then the Governor of South Africa, a grandson of Queen Victoria and the cousin of King George V.
There was a plaque on the wall of the 'Tin Hat' but it's long gone, though people assume it was a WWI memorial, which doesn't seem to be what was intended when it was built, but people have since considered it as such.
It was designed by JJ BURT, the Assistant City Engineer.
The second picture shows the pair of identical domes that stand on either side of the King George V Colonnade on the promenade at Bexhill-on-Sea. It is often (incorrectly) thought to be part of the landmark that stands behind it - The De La Warr Pavilion (see weblink above.) which wasn't even built until 1935.
However, the Colonnade was built in 1911 to commemorate the coronation of George V. Refurbished in 2011, it was always been painted in pristine white and is one of the most photographed locations on the south coast of England. It was designed by the architect JB WALL.
(I wondered if perhaps JJ BURT had been a pupil or colleague of JB WALL, and had subsequently gone out to work in South Africa. I searched through the East Sussex County archives online - and discovered that JB Wall also built several houses in Bexhill in the 1900s (many of which still stand today) suggesting he had a substantial business but I've been unable to find anything about JJ BURT so the connection remains a mystery.)
