This reservoir was built to collect the water of several unfailing springs that issue from the foot of Glastonbury Tor - a crumbling stone plaque between the middle two buttresses proclaims that it has a capacity of 137700 gallons. In the 1980s the building was (controversially) sold to a private businessman who set up a rather dank cafe within the windowless building and bottled the water to sell as Glastonbury Spring Water. I was interested to find that the cafe of my childhood memories is no more, and the building currently houses an all-welcoming "new age" shrine - see ST5038 : New Age Shrine Glastonbury - described by its custodian as an "Avalonian temple beyond compare".
