In the novel 1984, what is the contrast between the Ministry of Truth building and its surroundings? What does it point out about this society?

The contrast between the Ministry of Truth building (and other ministry buildings) and its surroundings is that the Ministry building is huge and new while everything else is old and run-down.

The Ministry building is 300 meters high and pure white.  The surroundings are made up of old buildings, patched and propped up.  There are also all kinds of craters from bombs.

This shows how completely the government dominates the society of Oceania.  Only the government has new and imposing buildings because only the government is seen as important.  The buildings, like the government, completely overshadow the rest of society.
