No, the Mersey tunnels are major engineering works and have only been possible in modern times.
Rivers, by definition, are natural. Many, including the Mersey, have been widened and dredged by humans to make them more useable for commerce.
I cannot tell you if there still are sharks in the river Mersey but in 2008 there was a baby shark caught by two fishermen and near the end of 2010 a BBC radio presenter was on google earth and typed in Albert dock were he discovered a large shape in the water and it's been said it could have been a basking shark. It eats plankton so it is harmless.
There are people that have been known to live in underground tunnels. These are generally occupied by people who are homeless and who have no where to live.
blah blah blah
Yes, there are a lot of underground tunnels in Victoria. You don't want to go down there. Yes you do. They're dark and creepy, and they go on forever, turning corners and ducking under streets, and the openings are right under your nose. People have been occupying them for decades.
Tunnels were built under the Sphinx for various reasons, including archaeological exploration and historical research. Some theories suggest that these tunnels may have been constructed by ancient civilizations seeking to access hidden chambers or artifacts. Additionally, modern excavations have revealed these passages as part of efforts to understand the Sphinx's construction and its historical context. However, the full purpose and extent of the tunnels remain a subject of speculation among historians and archaeologists.
People have lived on the site where Paris is located for thousands of years. One reason is the river that runs through the city. Today and in the past water has always been important for drinking, fishing, and shipping/movement. There layers of the past under the modern city and under Paris are caves and miles of tunnels. These have been used to hide things, bury the dead, and to move people through the tunnels.
woodside, because it is right by the river mersey but it could be livepool because the river mersey is in the middle of liverpool+the wirralMy daughter came home from primary school today saying that the olympic torch was actually in Asda Arrowe Park today, her class had been taken this afternoon, she did have some olympic pens, keyrings and bits and bobs, and her and her friends decided to go straight back up there after school.Not sure if its the real thing however.
Tunnels were always present, most weren't discovered or advertised until later in the war. Tunnels have been used my most armies thru-out history, they are NOT unique to just the Vietnam War. One of the biggest tunnelling events occurred during WWI when British forces tunnelled underground to go under a German position and place explosive charges under it. It was one of the largest explosions of the war.
the tunnels were used for storing food because it was cool and as an escape route.I have never been heard of them being used as a way to set the castles on fire but i would have been motte and bailey castle because they were made of wood.
There are many rivers that have been pushed underground in London.
The Cataphiles use the tunnels for a number of reasons. They dig vents, make maps, and take their time exploring the tunnels. They have also painted murals, and like to take pictures of the different sections of the tunnels. Others have been known to sneak into the tunnels to throw wild parties or to meet someone on a secret date.
