The spa baths that put the Spa into Woodhall in the 19th century have been empty and decaying since their closure in 1983. The original shaft was sunk in 1821 in search of coal, but a salt water spring high in iodine content was discovered instead and the coal shaft was abandoned in 1822. During the 1820s and 1830s a local landowner developed it into a bath house with 6 treatment rooms and a hotel. In 1887 it was purchased by a business syndicate who added wooded gardens and walks. Over the years interest in 'taking the waters' diminished but it continued to be used by the health services until 1982. On 21 September 1983 the well wall collapsed, undermining and causing the collapse of a large chimney which in turn damaged some of the buildings. The well was later filled with the rubble.
