YDYCH CHI`N DDIGON DEWR I`W CHROESI?

The blog title above translates to Are you brave enough to cross it?
At over 1,000 feet long and 130` high - choose your own height, have seen 4 different versions in print but if you fall a couple of foot either way won`t help you- this is truly a remarkable piece of engineering. No cranes or JCB`s 200yrs ago when this beauty was built.
The stone pillars are solid for the first 70` and then hollow to the top. This was to save weight on the foundations. Blocks of stone are bound together by a mixture of Lime, Water and Oxen blood so next time you build a wall in the garden pop into B&Q and get a bag of this mix and your wall will still be there in 200yrs.
Telford built this marvel in 1795 and it opened in 1805. If you look back to the blog of April 22nd and go to the comments you will find a lot of info on the aqueduct. My thanks go to whoever put this on the comments.

Andy/Tina following me across and Tina is standing on the towpath side away from the edge of the iron trough. On the way back she stood on the other side saying she preferred seeing the drop as opposed to the feeling of looking ahead and the boat appearing to be in flight.

Just 2` behind where i am standing this is what is between me and a long drop down.

This view from the Ponty Aqueduct shows a stone viaduct in the distance which i assume carries a railway across the valley.

Here are some views as we cross the Pontcysyllte Aqueduct that spans the valley and the Afon Dyfrdwy ( River Dee)
