St Kilda is a inner city suburb of the Victorian capital of Melbourne, Australia. It is located on Port Phillip Bay about 7 km south-east of the Melbourne's central business district. It has the largest population of any suburb in the City of Port Phillip. The suburb has been a popular seaside resort for residents and visitors since its foundation. During the Edwardian and Victorian eras it was favoured by Melbourne's elite, and many palatial mansions were constructed. Subsequently the area became Melbourne's red-light district, with many of the large mansions converted into low-cost rooming houses. In recent years, St Kilda has begun to shake off a seamy reputation and is home to many of Melbourne's famous visitor attractions including Luna Park, the Esplanade Hotel, Acland Street and Fitzroy Street. It is the home of many theatres and St Kilda Beach and to many of the city of Melbourne's big events.
