The Charles Bridge is a historic, gorgeous bridge that crosses the Vltava (Moldau) river in Prague. I was fascinated by it and the whole city of Prague when I visited.
Its construction started in 1357 under King Charles IV, and finished in the beginning of the 15th century. It stands today – which means it has seen an amazing amount of history.
The associated video collection on the channel also goes through how the bridge was constructed – and has videos of other historic Prague buildings.
