The Päijänne Water Tunnel (Finnish: Päijännetunneli, Swedish: Päijännetunneln) is a water tunnel located in Southern Finland. At 120 kilometers (75 mi), it is the second-longest tunnel in the world, running at a depth of 30–100 metres (100–330 ft) in the bedrock.The purpose of the tunnel is to provide fresh water for the over one million people of the Greater Helsinki area, including the cities of Helsinki, Espoo, Vantaa, Hyvinkää, Järvenpää, Kerava, Kauniainen, Kirkkonummi, Sipoo and Tuusula. The former Porvoo Rural Municipality, now merged with the municipality of Porvoo, also took part in the building of the scheme but has never drawn water from it for domestic use. The tunnel starts at Asikkalanselkä in Lake Päijänne, the second-largest lake in Finland with an area of 1,080 square kilometres (420 sq mi). From there, the tunnel slopes slightly downhill allowing water to flow naturally with gravity. Water from the southern portion of Lake Päijänne is of good quality at the tunnel intake, and usually drinkable without processing. The tunnel ends at the 0.5 square kilometres (0.19 sq mi) Silvola reservoir in Vantaa. From the reservoir, water is pumped to water treatment plants in Pitkäkoski and Vanhakaupunki. Since the constant low temperature in the deep tunnel ensures high quality during transport, only minimal processing is required before use.The construction of the tunnel started in 1972 and was completed in 1982, at a cost of approximately €200 million (adjusted for inflation). In 1999 and 2001, portions of the tunnel required repair due to rock falls. In 2008, the tunnel underwent an extensive renovation. The southern part of the tunnel was reinforced in order to prevent cave-ins. During the renovation, the Vantaa River was used as an alternative water supply for the Greater Helsinki area. The tunnel has a cross section of 16 square metres (170 sq ft), wide enough for a truck to pass through, enabling a water flow of 10 cubic metres (350 cu ft) per second. It takes approximately nine days for the water to traverse the length of the tunnel. At current water usage rates, treatment plants take water at a rate of about 3.1 cubic metres (110 cu ft) per second for drinking water processing. The tunnel can be used as an emergency water reserve during water supply disruption.

Kannelmäki
Kannelmäki

Kannelmäki (Swedish: Gamlas, Helsinki slang: Kantsu) is a sub-neighbourhood of the neighbourhood of Kaarela in Helsinki, Finland. Kannelmäki is located a bit more than ten kilometres from the centre of Helsinki, and is bounded by Kehä I in the south, Hämeenlinnanväylä in the east, and the Mätäjoki river in the west and north. It is a part of the Western major district. In early 2006, Kannelmäki had 12 488 inhabitants.The streets in Kannelmäki are named after music and villages in Ostrobothnia. The area was originally named Vanhainen – Gamlas, which comes from the village of Gamlas originally located at the site, and its Finnish translation. Because of the wishes of the local inhabitants, the name was changed to Kannelmäki – Gamlas in 1959. The singular church of Kannelmäki was completed in 1968.Services in Kannelmäki are concentrated in the shopping centre designed by Erkki Karvinen and opened in 1959, the Prisma hypermarket building (originally opened in 1973 as Eka-Market, then as Maxi) and the surroundings of the Kannelmäki railway station. Prisma was expanded into a larger complex called the Shopping Centre Kaari in October 2013, now containing a department store, a restaurant area and about 80 specialty stores. It is the fifth largest shopping centre in the Greater Helsinki area and the ninth largest in Finland. The Kannelmäki railway station is one of the stations on the Ring Rail Line. It is located next to the cultural centre Kanneltalo.

Myyrmäki Church
Myyrmäki Church

Myyrmäki Church (Finnish: Myyrmäen kirkko, Swedish: Myrbacka kyrka), is a Lutheran church in the Myyrmäki neighborhood in the city of Vantaa. It is located near Louhela commuter train station. The church was designed by architect Juha Leiviskä and it was opened in 1984. It is also known as the Church of Light. In Leiviskä's own words: "To me, a building as such, 'as a piece of architecture', is nothing. Its real significance is revealed in counterpoint with its surroundings, with life and with light."In addition to the actual sanctuary, the building houses a separate chapel, two meeting halls, the parish offices, and facilities for children’s and young people’s ministries. The sanctuary seats 450, but with the adjoining meeting halls the capacity is over 700.Vantaankoski Parish is one of seven Evangelical-Lutheran parishes in Vantaa with a membership of c. 30,000. Myyrmäki Church is the main church of the parish.The organ of Myyrmäki Church was built by Kangasalan urkurakentamo in 1986. The sound of the organ is mainly Baroque in style.Leiviskä has stated that when designing the church the ideal he had in mind was the Neresheim Abbey in Bavaria, southern Germany, the late Baroque church designed by architect Balthasar Neumann. The British architecture historian Kenneth Frampton has discussed this aspect of Leiviskä's church architecture, stating: "The Baroque churches of Southern Germany are the conscious inspiration for these (church) works, as Leiviskä openly concedes, even if the syntax could hardly be more removed from the plasticity of Balthasar Neumann. An indirect, hypersensitive play of light on a set of highly susceptible layered lattices and planes is patently the aesthetic modus operandi in these churches. And to this ludic game we must add the equally playful layering of lights miraculously floating at the ends of imperceptible cords..."
