The Altar of Dionysus is located in the capital Kos Town
, it’s less than 10 minutes walk from the harbour, not far from the Ancient Agora
and across the road from Casa Romana
The site itself is just 2500 square metres, there’s no entrance fee but there is an information sign to let you know what you’re looking at.
The site dates back to the 2nd century B.C. so roughly 2200 years old and consisted of a stone built temple and altar. There’s a number of columns scattered around the rectangular altar and some foundation stones.
The Altar of Dionysus is set in a sunken L shaped area surrounded by trees, there’s around a dozen steps leading down to the grassed section where the Altar and other remains are located. You can easily see the entire site in under an hour so it can be combined with a trip to the other sites in the area.
There’s a couple of car parks that you can use in the area, one to the north east of the site that’s really small and a much larger one just south of the site, this is your best option, particularly if you plan on visiting Casa Romana as it’s right next to it. There’s also road side parking.
