The original lyrics to the nursery rhyme “London Bridge is Falling Down” are:

Verse 1: London Bridge is falling down,
Falling down, falling down,
London Bridge is falling down,
My fair lady.

Verse 2: Build it up with silver and gold,
Silver and gold, silver and gold,
Build it up with silver and gold,
My fair lady.

Verse 3: Silver and gold will be stolen away,
Stolen away, stolen away,
Silver and gold will be stolen away,
My fair lady.

Verse 4: Build it up with iron bars,
Iron bars, iron bars,
Build it up with iron bars,
My fair lady.

There are many variations and additional verses to “London Bridge is Falling Down,” with some versions referencing other materials (like wood, stone, or clay) being used to rebuild the bridge, followed by the idea that they will also fail. The song has origins in medieval England and has evolved over time.
