The letter H represents Houses of Parliament and depicts a crowned portcullis with chains (an adaptation of the Badge of Henry VII which is now the Badge of the Palace of Westminster).

A portcullis (from the French porte coulissante, "sliding door") is a heavy vertically-closing gate typically found in medieval fortifications, consisting of a latticed grille made of wood, metal, or a combination of the two, which slides down grooves inset within each jamb of the gateway.

The Palace of Westminster is the meeting place of the House of Commons and the House of Lords, the two houses of the Parliament of the United Kingdom. Commonly known as the Houses of Parliament after its occupants, the Palace lies on the north bank of the River Thames in the City of Westminster, in central London. The Palace is one of the centres of political life in the United Kingdom; "Westminster" has become a metonym for the UK Parliament, and the Westminster system of government has taken its name after it. The Elizabeth Tower, in particular, which is often referred to by the name of its main bell, Big Ben, is an iconic landmark of London and the United Kingdom in general, one of the most popular tourist attractions in the city, and an emblem of parliamentary democracy.
