Leaning Tower of Pisa, IT
The foundations went down on 9 August 1173
The foundations went down on 9 August 1173. Construction took 199 years across three stages, because the Republic of Pisa kept going to war — with Genoa, with Lucca, with Florence — and the work stopped for most of a century. The attribution has moved between a man called Guglielmo and Bonanno.
