The small village Hosín lies about 3 km north-west of the town České Budějovice above the Českobudějovická Pánev basin (České Budějovice Basin) on a small hill (508 m a.s.l.) with nice views of the town, the Hluboká nad Vltavou chateau and the Šumava mountains (Bohemian Forest).
The Pseudo-Romanesque Church of Sts. Peter and Paul from the turn of the 20th century stands in the village. In this place a small original Romanesque church stood and it was reconstructed as a side chapel of sacristy to the new church during the Gothic period. It was torn down in 1898, only the sacristy was saved, and the present church was built.
The building has a unique appearance due to the glazed fully-fashioned fireclay bricks.
The remains of the former kaoline mine called Orty can be found about 1.5 km south-east from the village.
