The House of Magnates (Hungarian: Főrendiház; German: Magnatenhaus; Romanian: Camera Magnaților; Italian: Camera dei Magnati) was the upper chamber of the Diet of Hungary.

The House had no fixed membership size, as anyone who met the qualifications could sit in it.

The shaping of the House of Parliament grew out of conscious choices of symbolism and carries important historical and political messages.

Viewing it from the side of the Danube, we see the halls of the lower and upper houses rise on both sides of the dome surrounded by turrets, which evoke the memory of the bicameral parliament that was in operation when the building was being constructed.

The dome rising between them signifies the unity of the legislature as well as serving as the venue for joint sittings of the two chambers.
