Unbelievable canals around the world and their major roles

Grand in scale and beautifully imagined, the original Panama Canal is an engineering marvel. — Photos: Handout

There are plenty of large canals around the world that are worth visiting. I particularly love to stand by a canal, watching one huge ship after another slowly sail before my eyes.

Staring at the nearly 20,000 colourful containers stacked 40 storeys high – making them look like Lego towers – can be quite an experience too.
