This is the inside of the oldest greenhouse - I know this is not a very interesting photo aesthethically, but look at the plant benches - they are all cast iron, with stone slab tops. Underneath the central one is a water trough, lined with stone slabs, and fed from the run off from the glass roofs. You can dip a bucket or use a pump to draw the water off - there is a diverter to stop any further water coming in so it doesn't over flow. Amazing.
