yes - really interesting - you'd have got the nice sunny blue picture earlier but I was googling (unsuccessfully) useful things about Mezen to use as clues and came across it
I knew the Google Wizards here would get it in a flash - hence the fog shrouded picture
Never went - a colleague did go in the early '00's looking to see if you could use it the harbour to land large pieces of kit .... no - but he did mention the Tower to me . I was working more around Murmansk & Archangel................
