Lohja is situated in the western part of the Uusimaa region. The population of Lohja is approximately 45,000. It is the 25th most populous municipality in Finland. Lohja is part of the Helsinki sub-region, but not directly part of the Helsinki metropolitan area. Lohja covers an area of 1,109.73 square kilometres (428.47 sq mi) of which 91.78 km2 (35.44 sq mi), or 8.3 percent, is water. The population density of Lohja is 48.33 inhabitants per square kilometre (125.2/sq mi). Lohja has the fourth most summer cottages of any municipality in Finland, with 8,468 in the city as of June 2018. Lohja is close to the Helsinki metropolitan area and benefits from a good road network. It takes less than an hour to drive from Helsinki to Lohja on the E18 motorway, which, along with Hangonväylä, is one of Lohja's main road connections. Lohja is a bilingual municipality with Finnish and Swedish as its official languages. The population consists of 89% Finnish speakers, 3% Swedish speakers, and 7% speakers of other languages. City's bilingual slogan is: Järvikaupunki – Insjöstaden which translates to "Lake city". The landscape of Lohja is characterized by manors and gardens. Its area is divided by the Lohja ridge, which forms a watershed for the largest lake system in Uusimaa, Lake Lohja (Lohjanjärvi); mostly that's why Lohja is also referred to as "Lake City" (järvikaupunki). The medieval Church of St. Lawrence is the architectural highlight of downtown Lohja, which also includes a heterogeneous mix of buildings mostly dating from the 1960s onwards. The Lohja library, which was opened in 2005, is a distinctly modern building placed in the very centre of the city.[citation needed] Lohja has been a focal point for the population and economy of western Uusimaa since the early 14th century. It was renowned as a trading centre in the Middle Ages.[citation needed] The local inhabitants were among the pioneers of the Finnish mining and construction material industries. Lohja has long-established traditions in horticulture and especially in market gardening. These traditions are represented by the symbols of present-day Lohja: limestone and an apple.[citation needed]
