This was my Mom's bird bath, now in its new home in our little entry garden. An heirloom of sorts.
It's big and deep enough to give a kid a bath in it. easily holds 8-10 gallons. Cast iron, too heavy for me to lift even the top alone, much less to seat it into its slots. It has a drain plug in it, and it's decorated with three dragons. The base has a bit of rust damage to the surface. I had to power wash it, spray it with Rustoleum and then with a coat or two of black. A delicate sand-blasting might have been better, but I thought that might be too much for the detailed ornamentation of the base.
It could have been forest green (and maybe used to be), but I went with black to be safe.
Like my Mom, Mrs. BD understands the structural requirements of garden design. Focal points, structured areas, plantings for interest each season, etc. We do gardens.
