Aamadu Bàmba founded Touba in 1887. The holy site remained a tiny, isolated place in the wilderness until his death and burial at the site of the Great Mosque, 40 years later. The Great Mosque was finally completed in 1963 and since its inauguration the city has grown at a rapid pace: from under 5,000 inhabitants in 1964, the population was officially estimated at 529,000 in 2007.[citation needed] Along with the neighboring town of Mbacké (founded by Aamadu Bàmba's great-grandfather in 1796), the Mouride conurbation is Senegal's second largest urban area, after the capital region of Dakar.
