Random neat idea, reading a thread on pigeons, a link to an article on dovecotes, and look what I found!!
It's a revolving ladder, so you can reach in all the nests...
I want a round tall tower for my library, and a revolving ladder in it! Wouldn't that be AWESOME?!
Not this year, and probably not the next 15 years either... but a LOVELY pipe dream!!
So I'm thinking a tower like that, needs big stained glass windows up high, and a roof I can sit on, and put vines cascading down the sides, with floor to 20 foot high bookshelves accessed by a revolving ladder :)
Yay! Pipe dreams in the morning.
