A charred and blackened meadow at Hartsholme Park is a stark reminder of the dangers of dry grassland in the current persistent heatwave.
Four fire crews from Lincolnshire Fire and Rescue rushed to the scene and managed to extinguish the blaze, which sent clouds of smoke into the air around the country park.
Residents of the nearby Jarvis House tower block viewed from above as the fire spread quickly across the ground.
Ruth Holland from Lincoln visited the park to find ash reaching almost entirely across the meadow.
Firefighters have yet to determine a cause of the blaze.
A warning was issued earlier in the week following a number of grassland fires in the county.
On a number of occasions, dry open spaces were set alight by carelessly discarded cigarettes.
Lincolnshire Fire and Rescue crews from Spalding and Skegness recently joined colleagues to tackle blazes at Saddleworth Moor near Manchester and Winter Hill near Bolton, along with hundreds of firefighters from across the country.
