Two points of this world heritage site are just outside the village of Simuna, 41 km south of Rakvere.
The Struve Geodetic Arc is a chain of survey triangulations stretching from Hammerfest in Norway to the Black Sea, through ten countries and over 2,820 kilometres (1,750 mi), which yielded the first accurate measurement of a meridian arc.

Võivere
In the middle of a field next to the Ebavere-Simuna road stands the only building left of the Võivere manor. It's a windmill that served as a triangulation point and has now been restored into a visitors' centre. Next to the windmill is a marker in the ground protected by a vitrine.
The next point is not far from the former, just east of Simuna along the road to Paasvere there's a little stone pillar in the field marking the end of the Simuna line.
Voore mõis
The manor house slowly wilts. The interest part is a stone barn of the 18th century with five semicircular arches. The building is unexpectedly large and carefully designed from an architectural point of view.
Inju mõis
A remarkable manor house in the style of neo-Renaissance, built in 1894.
Mõdriku mõis
A large manor house with a central building in the spirit of classicism. In addition, there is a landscape park with ponds and a war memorial of 1812.
Mädapea mõis
A brick building in the style of neoclassicism, built in 1850. Inside a collection of paintings and objects of everyday life can be found. When agreed with the owner, a look inside is possible.
