Youngest son J and his partner went to Sydney last year. They took a cruise along the river and took these photos of the Sydney Opera House in Sydney, NSW, Australia.
This tunnel below was built between 1913 - 1936 to carry submarine electricity cables for the electric tramway system on the north side of the harbour as submarine cables laid across the bed of the harbour had suffered damage from ships and their anchors.
The tunnel became flooded in 1930 and remained in use until 1969. If interested, you can read more [ here ] I left the tunnel as it was because it looks spooky.
