The small village Strašín lies near the border of the Protected Landscape Area Šumava (Bohemian Forest) about 10 km south-west of the town Sušice and 6 km north-west of the small town Kašperské Hory, 605 m a.s.l.

The priceless (originally Romanesque) Church of the Nativity of Virgin Mary stands on the outskirts of the village. It dates from the middle of the 13th century. In the second half of the 14th century (1369) it was known as a parish church. In the middle of the 15th century Půta Švihovský, the owner of the contiguous Rabí castle, had the church reconstructed. The current look is from the big Baroque reconstruction (1736 - 1739). After that it became an important pilgrimage place.

The three-aisled church with a square closed presbytery joins two low towers on the eastern side and a big one on the western side.

The alley runs to the church, marked with the green sign (leading from Kašperské Hory through Strašín to the town Strakonice).

The Strašín Cave, one of the biggest caves in south-western Bohemia, lies in the surroundings of the village near the road to the town Sušice.
