Chimneys

And lots of them. Expensive to maintain and most of them need it seeing as how they were built in 1846. It takes a brave person to go up their and work on them without scaffolding and there are still some people that will. Actually it takes a brave person to work up there with scaffolding! Thankfully only one is mine but we share a flue or two with the highest and blackest one at the back. Here is hoping it lasts a bit longer.
