Hohenrätien Castle, Medieval castle ruin in Sils im Domleschg, Switzerland.
Hohenrätien is a castle ruin in Sils im Domleschg, Grisons, perched on a rocky spur high above the valley floor and overlooking the routes connecting the Rhine valley to the surrounding Alpine passes. The complex includes stone walls, the Church of St. John with its baptistry, and open areas that can host events.
The rock was already settled in the Bronze Age and through Roman times, and a castle began to take shape here in the 11th century, when control over the pass routes mattered greatly. Over the following centuries, ownership changed several times before the complex fell into disuse and became the ruin visible today.
The Church of St. John inside the complex served as the main parish church for the left bank of the Rhine until 1500, drawing worshippers from a wide area around the valley. Its walls and the adjoining baptistry are still standing and give the site its most recognizable shape today.
The path up to the ruins is steep and crosses rocky ground, so sturdy footwear is a good idea before you set off. Allow extra time for the climb and the visit itself, as the uneven terrain means moving between the different parts of the site takes longer than expected.
Before the site became a Christian place of worship, a Roman temple likely stood here, possibly dedicated to the god Mithras. This sequence of religious use on the same rock, from ancient shrine to early church, makes it one of the oldest layered sacred sites in the region.
