“The most unusual place that I visited abroad was in Paris a few years ago. I took a tour of the sewers and joined a group of about 20 tourists underground, to discover large, wide spaces mirroring the avenues above.

These spaces were all vaulted and underneath ran what looked like an artificial river, where filtered and clean drainage passed. Each underground avenue was named after the road above it.

We were even shown the sewage pipes attached to famous people’s houses above. I found the tour very interesting although the smell was at times a bit overpowering.

However, I would still take this tour all over again if I have the time, next time I visit my favourite European city.”
