Site Name: Blackwater Green Forge (Worth Hammer) OS Reference: TQ 2912 3624
Click here to view on Where's The Path
Parish: Crawley Former Parish: Worth
Hundred: Buttinghill District: Crawley
County: West Sussex River Basin: Mole
Site Type: Forge Period: Modern
Century: 17, 16 Geology: Upper Tunbridge Wells Sand
Geology notes:
Earliest known date: 1549 Latest known date: 1617
Dating evidence: This is likely to be the 'hamer at Worth' mentioned in the accounts for Worth and Sheffield in 1549 (Giuseppi 1912, 299), and in the inventory of ironworks belonging to the Lord Admiral, Sir Thomas Seymour, in the Forest of Worth in the same year (Ellis 1861,128-31). Blackwater is probably one of the two hammers in Moore (Worth) Forest in the ownership of Lord Abergavenny, let to John Caulfield alias Eversfield of East Grinstead in 1574 (Cattell 1979:166), there being difficulties in determining the division and descent of ownership of the forest. Deaths of vagrants at Worth Hammer were noted in the Worth Registers in 1584 and 1588. With Worth Furnace, it is probably the forge leased by Edward More in 1617, rather than Tinsley as has been suggested elsewhere.
