The ground inside the dome is noticeably curved downward.

Thanks again, John. These are always very interesting.

Looks a bit like an ice house.

Aha, it is.http://openchiswick.squarespace.com/...-visit-/*says:
"the strange little semi-circular structure which can be seen in Grove
Park Terrace is all that remains of an ice house – a building used for
storing ice and for keeping food cool in the days before refrigeration.
It was originally a hollow brick dome covering a circular underground
chamber. This ice house probably belonged to the large mansion called
Sutton Court (demolished c 1900)."

And here it is Polish:http://fotoforum.gazeta.pl/72,2,888,...,67347146.html

I am not exactly sure, but this photo from Poland (how did he find
it?) seems to have sparked quite a lot of comments.
My Polish is a little rusty since the collapse of communism, and I
could not get sense out of Google-translate. I wonder what those crazy
coal-crunchers are on about?
