Later, in 1861, when the railway reached Buca from Smyrna, many rich Europeans from Smyrna built their summer houses in Buca. Yet, due to its substantial growth, Buca soon became a suburb of Smyrna and people started to stay there permanently. At the beginning of the 20th century, there were three Greek Orthodox churches, two Greek community schools (one for males, one for females) as well as some private Greek schools also, while there were two private English schools, one catholic nonnes' school and one Capuchin monks school. The Greeks, together with other Christian inhabitants, constituted the majority of the local population, while Muslim (Turkish) population was very small. However, Greek inhabitants were expulsed in 1922 and fled to Greece, where they named their new settlement "Neos Voutzas" (meaning "New Buca"), close to Athens. As a result, there are today only a Catholic and a Baptist church in service in Buca. Many of the 19th-century houses have been restored and are still being used either by public institutions or by private persons, although many still need care. The core area of Buca could preserve its traditional architectural tissue based on two-storey residences, while apartment blocks mushroomed in its extensions, as it is the case in all localities in Turkey which had to absorb immigration. There are a number of municipal parks, notably a vast ongoing project that comprises seven artificial lakes.
