Belsize Park woke up to the sound of clucking hens and the smell of smoking cob ovens last weekend.

A pop-up urban festival was held on Haverstock Hill on Saturday with lessons in back-to-basics agricultural skills.

Passers-by taught how to make jam and how to keep chickens and were taken on edible plant walks.

Punters could also make their own pizzas in a cob oven, which can be built from materials found in your back garden.

On the same day, Camden Friends of the Earth hosted an eco-friendly treasure hunt across the borough.

Enthusiastic treasure seekers used only sustainable transport to hunt out clues, beginning at Camden Market and ending at the urban farm festival.
