The Hungarian Parliament Building (Hungarian: Országház, which translates to House of the Country or House of the Nation) is the seat of the National Assembly of Hungary, one of Europe's oldest legislative buildings, a notable landmark of Hungary and a popular tourist destination of Budapest. It lies in Lajos Kossuth Square, on the bank of the Danube. It is currently the largest building in Hungary.

The Széchenyi Chain Bridge is a suspension bridge that spans the River Danube between Buda and Pest, the western and eastern sides of Budapest, the capital of Hungary. Designed by the English engineer William Tierney Clark and built by the Scottish engineer Adam Clark, it was the first permanent bridge across the Danube in Hungary. It was opened in 1849. The bridge has the name of István Széchenyi, a major supporter of its construction, attached to it, but is most commonly known as the "Chain Bridge". At the time of its construction, it was regarded as one of the modern world's engineering wonders.
