Medieval Candlestick Tower

I had this potpourri bowl with a pewter lid that my wife picked up for me from somewhere.  The lid is destined for a wooden bowl that I'll turn (or have - she's since picked up a couple more) but that left me with this glass bowl.  She asked if I could make some sort of candle holder using the glass bowl ... and out of that was born this idea.  

It's a fairly simple carving, but it takes a long time to do.  I turned the basic shape, and then hand carved each stone, the windows, and the door.  I haven't had much experience in painting carvings, but I had fun with this one.  Below is a detail shot of the lichen/moss I added to the carving with paint.  I used acrylics.
