Marble Arch

Marble Arch was designed by John Nash in 1828, and was originally intended to be the entrance to Buckingham Palace. This didn’t come about, largely because the dimensions of the arch were not appropriate to the vehicles that would have to go through it. Marble Arch is therefore something of a stand-alone monument now.

Marble Arch is something of a stand-alone monument

With plenty of intricate carvings and design

Clearly a lot of work went into producing the Arch

I don't quite know how long it took to construct

But it isn't used now for its intended purpose, as an entrance to Buckingham Palace
