A landscape with two centres

Pertunmaa is best approached as a lake-and-forest district rather than a single compact town. The former municipal area lies in southern Savo, close to the cultural border with Häme, and its two main settlement areas still give visitors different ways in. The church village rests among the lakes and local services; Kuortti, roughly ten kilometres away, faces the constant movement of Highway 5. The road stop is convenient, but it is not the whole story. A short drive separates it from the quieter lakeshore centre, where Pienivesi, Peruvesi and the Pankajoki shape the walks and everyday scenery.

There is an important date to keep in mind when reading older guidebooks. Pertunmaa ceased to be an independent municipality on 31 December 2024 and joined Mäntyharju on 1 January 2025. The last municipal-area population figure used here is 1,527 residents on 31 December 2024. It describes the whole former municipality, not the church village alone and not present-day Mäntyharju. The former area covered 454.3 square kilometres, with lakes and ponds making up about one-sixth. A local publication recorded 1,733 second homes in 2023, one reason the place’s rhythm changes with the seasons: permanent residents share the landscape with cottage owners and summer visitors.

From rural parish to a changing municipality

The name Pertunmaa carries a long local history, but the documented civic story is more recent. The former municipality dates its establishment to 1926, after the parish had separated in 1924. This is the point at which a distinct local administration took shape; it is not evidence of an ancient town foundation. The countryside around the settlements has long been worked and travelled, and the 2024 local publication remembers slash-and-burn farming in the district’s heraldic imagery. Forestry, farming and local services belong to the area’s rural history, while the Highway 5 corridor gives Kuortti a role as a place to stop, refuel and provision a journey. Today, lakeside recreation, holiday homes, small visitor businesses and community life add to that picture, without replacing the working character of the villages.

The 1929 wooden church is a striking marker of how the area built with what it had. Designed by building master Matti Vihonen, it is a short-armed cross church with a tower. Some of its timber came from the old church in Hartola and from a temporary prayer house. Local information says volunteers moved the logs by horse in about 300 loads. The church remains in use as part of Mäntyharju parish, and the small historic trail through the church village links it with local stories, the old village, the Pankajoki bridge and the former sawmill. Ten information signs make the roughly one-kilometre walk an easy introduction to the centre.

A grave that opens a question, not a foundation myth

Near the Vanha-Rantala farm, a burial mound found in 1928 was excavated the following year. Jewellery, glass beads and a small knife led archaeologists to interpret it as the grave of a wealthy woman from around AD 1000. That discovery complicates the assumption that the wider region was uninhabited wilderness at the time. The museum notes that a fur-trading station enriched by trade is one possible explanation. It remains a hypothesis, not a proven account of the grave or the origin of Pertunmaa. The objects are in the National Museum of Finland’s collections; Vanha-Rantala keeps a small archaeology display and a memorial stone in the farmyard.

The museum itself makes the story tangible through a different kind of evidence. The farm belonged to the same family from 1665 to 1964. Its main room dates to the eighteenth century, while a later wing contains rooms furnished with textiles and furniture made by the household. Storehouses and a sauna remain in the original yard. The house became a museum in 1968 after having also served as a school and a travelling handicraft school for women. It is a compact way to see domestic life, work and skill across generations. Opening is seasonal: the 2026 dates have passed, so check the next season’s schedule before making the detour.

Walk the river, then link the villages

Pankapolku follows the Pankajoki for about five kilometres from Pienivesi toward Peruvesi. It is marked with turquoise signs and combines familiar village paths, forest-machine tracks, some road walking and boardwalks over wet ground. Kisaranta by Pienivesi is one starting point, with a fire site and a route map. The walk is not an inaccessible wilderness circuit, but it does cross both municipal and private land; visitors are asked to stay on the marked path, respect young forest and fields, and leave no rubbish.

For a longer outing, the marked Pertunmaa–Kuortti trail connects the church village with the roadside settlement over 12.5 kilometres. Nipuli lean-to lies five kilometres from the church village and 7.5 kilometres from Kuortti, making an out-and-back walk possible without covering the full route. The route has rest stops and a fire site, but there is no potable water at them. Wetland sections, slippery bridges and boardwalks, and exposed rock call for suitable shoes and attention, especially after rain or in colder seasons. At Kuortti, the Jokipellon tractor and agricultural museum offers a very different visit: dozens of restored tractors, hundreds of chainsaws and old household and farming equipment. It normally opens on summer weekends and can arrange visits at other times.

Getting there and planning a stay

By car, Highway 5 brings travellers to Kuortti from the Heinola–Lahti direction in the south or from Mikkeli in the north; follow the local road for about ten kilometres to the church village. Kuortti’s service station is listed as open around the clock, useful for fuel and a basic stop, while the visitor site lists local accommodation, walks and seasonal activities. Pertuntori, the lakeside market by Pienivesi, is a summer gathering place; its 2026 schedule ran on Saturdays, but each season’s dates are announced separately.

Public transport takes more planning than the main road suggests. Traficom publishes a Pertunmaa–Mikkeli service through 6 June 2027, with a morning departure from Pertunmaa and an afternoon return from Mikkeli on the service days shown in its timetable. Mäntyharju also runs local call-ahead rides between the church village, Kuortti and nearby settlements on set weekdays; the current routes require booking by noon on the previous working day. Check the timetable symbols, stop and reservation rules for your specific date. The railway station is in Mäntyharju, so a rail journey needs a separate onward connection. These details matter because the district’s attractions are spread out, and a cottage, trailhead, museum and grocery stop may not sit on the same route.

Pertunmaa rewards visitors who give the landscape room. Pair the church-village history trail and Vanha-Rantala with a gentle stretch beside the Pankajoki; use a second day for the full village-to-village walk or a lakeside stay. Kuortti handles the practical road stop, while the old centre reveals the slower scale of the place. Together, they show a community shaped by water, work, seasonal homes and the everyday decisions that keep rural places connected.
