The scenery of the Haralanharju ridge inspired author Zacharius Topelius to write the poem “Kesäpäivä Kangasalla” (Summer day in Kangasala) in the mid-1800s. The opening ceremony of the current observation tower was held in 2009.
The observation tower of the Vehoniemenharju conservation area is the oldest, dating back to 1927. The top of the ridge rises up to 60 metres above water level. The observation tower is located next to the Vehoniemi Automobile Museum.
The first observation tower in Finland was built on the Keisarinharju ridge near Mobilia in 1819 in honour of Emperor Alexander I’s visit. The current landing, titled “Keisarinportaat” (Emperor’s steps), is from 2006.
The functionalist tower of the Kirkkoharju ridge from 1930 is on the highest spot of all the towers, offering a stunning view of the Kangasala town centre. The tower was restored in 2000. Today, it is a popular venue for various summer celebrations and events.
