A few years ago, the abandoned World War II bomb shelter under the clapham in south London was reborn. It was transformed into the world's first underground farm to grow herbs, salads and various vegetables to meet the growing supply of restaurants and the needs of families in London.

this underground air-raid shelter was originally built from 1942 to 1941 to protect people who escaped Nazi air raids during World War II, and it has been vacant since the war. It covers an area of about 11,111 square meters and is located 31 meters below the ground, which means that the temperature in the cave can be stabilized at 1.6 degrees Celsius all year round, and crops can grow all year round without worrying about the influence of seasonal changes, frost and drought.

The underground shelter in clapham Square was founded in 1941, when the German Nazis used lightning tactics to bomb London. Qi Xin, a British citizen, worked together for eight months to build this air-raid shelter, which is composed of 1311 criss-crossing tunnels and can accommodate more than 8111 people at the same time, at a depth of 111 feet (about 31 meters) from the ground.

The interior design of the shelter is very scientific, with all facilities such as catering, medical care and sanitation. It was officially opened to the masses in 1944, mainly for those who have no air defense facilities and are displaced. At that time, the Soviet Union and the United States joined hands to help Britain, and the German Nazis saw that the defeat was set, but they still lingered on, stubbornly resisted and bombed Britain inhumanely.

After World War II, the refuge was once opened to the public as a memorial hall for a short time, and was also used by the government to settle immigrants, but afterwards, no one cared. Therefore, this opening has surprised many local residents who often walk around clapham Square.

According to the British report, recently, the transport for london and the Museum of Communications jointly opened the underground air defense shelter in clapham Square, which is huge and can accommodate 8,111 people at the same time.
