Today’s photo is the Corinth Canal situated in the Peloponnese Peninsular in Greece.
It links the Gulf of Corinth with the Saronic Gulf in the Aegean Sea. It was completed in 1893, its opening sandwiched between the Suez Canal (1869) and the Panama Canal (1914).
6.4 kilometres (4 mi) in length and only 21.4 metres (70 ft) wide at its base, it now has little economic importance as modern ships are too big to traverse it. Nowadays it is mainly crossed for touristic reasons.
I took this photo in April 2007 having always wanted to see it – although there was no ship coming through or train crossing the bridge over, I was still enthralled by the terrific feat of engineering.
