Tourism is not particularly developed in Lagos, yet the city's history resonates in its diverse architecture and in the names given to streets, communities, and districts. For example, Oke Faji, Popo Aguda, Campos Square, Pedro, and Martin Streets are steeped in Brazilian traditions, having been settled originally by Brazilian immigrants who started returning in the 1850s. Saro Town was land assigned by the Oba of Lagos to Sierra Leonean expatriates after the 1850s. The Shitta-Bey Mosque and the Holy Cathedral Church, both in central Lagos, also bear testimony to Brazilian architectural influence.
