Of course a very different word in local language, which is typical in Hungarian, you don’t get a clue as to what is what….
Országház, in this case.
Hmmm. Not close to the word Parliament in any sophisticated language I know.

Endre says it is among the oldest legislative buildings in Europe.
By size, it's the largest building in the country and the second largest parliament in Europe.
Construction started in 1885 was completed in 1904.
The architect, Imre Steindl, became blind during those years,
so the poor man never saw the finished building.
