I have been planning to take a group of visiting in-laws to various healing springs in South East England (related question [here][1]), and [St Helen's Spring in Hastings][2] seems like a great venue.

I have managed to acquire a great map to the spring as it's hard to find...
![enter image description here][3]

The 'x' on the map marks the location of a stone-built pool (presumably from the Victorian age) that captures and collects the water. The Trip Advisor site offers a [photo][4] of the pool, but gives scant information about it.  The main [Trip Advisor page for the spring][5] gives an alluring description, but again nothing specific.

The [Wikipedia][6] suggests that the stone-build pool may have been used in the late Victorian age as a baptismal pool.  And one [source][7] dates the construction of the pool to the 8th century, if not the [Sub-Roman era][8].

Question: can tourists (or even local visitors) immerse themselves here without fear of violating a rule laid down by the Trust? Or even a public law?  Is it ok to 'take a dip' there?

Note: I know (from the Trip Advisor link above) that the water is a constant 4 degrees year-round and taking a dip might be awfully cold, but surely if people were getting baptised there then it must be bearable.
