Firefighters are still monitoring a barn blaze at a Piccotts End farm.
Crews from Hemel Hempstead, Kings Langley and St Albans were called to Lovetts End Farm in Dodds Lane, Hemel Hempstead, just before 3.30pm on Wednesday.
The barn - measuring around 50m by 100m - contained straw and hay.
Firefighters used water jets to cool off the surrounding area to prevent the flames from spreading.
A crew is regularly visiting the site and will continue to do so until the fire burns itself out.
