tablishment of Piraeus as a municipality in 1835 and petitions from the new and emerging prosperous bourgeoisie, municipal elections were held to elect a mayor for the city, who was to be Kyriakos Serfiotis from Hydra. Piraeus had around 300 inhabitants at this time.
Piraeus, from a deserted small town, quickly became the leading port and the second largest city in Greece, with its prime geographical location and closeness to the Greek capital helping it continually to grow, attracting people from across the country. A number of events contributed to the development of the city ; amongst these were its ultimate declaration as the leading port of Greece, the completion of the Athens-Piraeus Railway in 1869, the industrial development of the area in the 1860s, and the creation of the Corinth Canal in 1893, all of which left Piraeus more strategically important than ever. New buildings were constructed to cover the necessities of this growth, such as educational institutions, churches, the Stock Exchange Building, the Town Hall, the Central Market, the Post Office Building and charity institutions; the port was also supplemented and modernised, with dredging operations, the construction of the Royal Landing, the Troumba Pier and the quay-ways up to the Customs House area, the commencement of construction work on the Outer Moles and the completion of permanent dry-docks. At the end of the 19th century Piraeus had a population of 51,020 people.
The establishment of the Port Committee in 1911, which controlled the works of construction and maintenance of the port, and the Piraeus Port Authority in 1930, which made a more efficient job of managing a port slowly increasing in traffic, played a catalytic role in the city's development. The town flourished and neo-classical buildings were erected; one of them, which continues to ornament the present town, stands as the Municipal Theatre, an excellent example of the area's once wider neoclassical architecture
