Camp Kizingo at Ras Serani: Military Base

The area roughly delineated by State House Mombasa and Mombasa Golf Club, known as Kizingo, was home in the late 1930s and early 1940s to the imperative and intricate military base, Kizingo Camp. On June 28, 1936, the Commanding Royal Engineer, Michael Biggs, took over the responsibility for construction work of Kizingo Camp. This included the construction of: two 6-inch guns in open concrete emplacements with ammunition embrasures, an underground magazine between the guns, two 36-inch high current density searchlights in concrete emplacements, an engine room, a three-storey reinforced concrete building, a Port Signal Station, and, on the domestic side, barracks (initially for 75 African askaris) and for the families of half of them, plus, an Officer’s Mess, Sergeant’s Mess, staff quarter, stores, administrative buildings as well as a sewage plant.

Most of the construction work was carried out by direct employment; the skilled work by Indian artisans (fundis). The hard manual labour, like the digging of trenches and chambers in the coral rock, was done by prisoners from the jail at Fort Jesus. “On December 21st, 1936, a successful gun test took place with a full load. The completion of the magazine, however, took longer. The last structure, completed in February of 1937, was the command post with its two main interconnected compartments for control of the guns and searchlights, with the big 9 inch Barr & Stroud rangefinder placed on the roof” – Hans-Martin Sommer.

In September 1939 war was declared and around Mombasa new activities began to protect the harbour and city. By September 1940, the probability of aggression increased with the signing of Tripartite Pact in Berlin between Germany, Italy and Japan. The Japanese entered the war in December 1941, and fears of an attack mounted steadily after Burma and Singapore were lost and Ceylon became the next target for the enemy. From there the East African coast was not far.

The main strategic concept was to defeat any Japanese fleet advancing against the East African coast through sea and air attacks initiated by the Royal Navy fleet based in Mombasa. Much of this was met by requisitioning public buildings and hotels like the Manor and today’s Castle Royal. The Royal Engineers again took the main responsibility for most of the renovation work and they were supported by groups of Air Force (Air Branch of the Royal Navy and South African Air Force) who were developing a big new airfield on the mainland close to Port Reitz, today’s Moi International Airport. The two guns near the light house, installed in 1937, were replaced by three modern 6-inch guns in power-operated turrets and with much greater range. Along Azania, a huge amount of defence work was installed.

Various harbour defences of smaller guns and searchlights covered both Kilindini Harbour and Old Port, and were linked to underwater submarine detection loops installed and operated by the British Royal Navy. South African Army dispatched about 500 men from an Anti-Aircraft Brigade to Mombasa in May of 1940. This 1st Unit was deployed in and around Mombasa at Nyali Bridge, Makupa Causeway, Port Reitz Aerodrome and the golf course. Each of these sections had two 3-inch anti-aircraft guns. The rest of the group arrived in June, and by month’s end, on the very verge of the war, no less than 27 posts in and around Mombasa were manned. After the Royal Navy code-breakers at Bletchley Park, UK, cracked the German Enigma Code, more efforts were made to decipher the Japanese codes.

In April 1942, following a Japanese attack on Colombo, most of the Royal Navy code-breakers in Ceylon moved to Mombasa. The Mombasa code-breakers, based at Ras Serani, enjoyed their first big success by helping to interpret the vital Japanese JN4O code. This and subsequent breakthroughs led to the Japanese trade marine suffering 90% losses by August 1945, victim to Allied submarines and bombers alerted to their presence. Despite the many efforts to keep the Japanese fleet away from the East African coast, Japanese submarines and aircraft targeted Kilindini a few times. Still and all, Japanese submarines and planes never attacked Kilindini. Likewise, no shot was fired on the Japanese from Azania Drive.

In May of 1945, the war in Europe was over and in September 1945 the Japanese officially surrendered. The defence of the East African coast was not solely in Mombasa’s hands. Installations had also been built in Tanganyika at Manza, Tanga and Dar es Salaam, and Zanzibar. All guns were fired after fitting for testing purposes only. It is reported that after the notice of the armistice the joy of the gun crews was so great that they loaded all the guns and fired. And fell silent forever!

Until about 1950, the cannons were still guarded by the King’s African Rifles and probably scrapped shortly afterwards. The ammunition was dumped 1.6 km off Mombasa’s coast. In 1960 divers recovered a portion of the explosives from the seaway and disposed of them. “Nearly all the defence buildings are today in a sad state. Only one site in Mombasa is still in use – and that is only as a public toilet.


Around Kenya are a selection of natural landmarks, cultural shrines, architectural oddities, and technological installations that offer incredible, almost surreal experiences that can make you feel as if you’ve stepped into another world. Hauntingly beautiful to some, eerie sights for others, and still, for others, down right strange, these site provide unique experiences for adventurous travelers.
