Thracian tomb Helvetia

The Thracian tomb known as 'Helvetia' is located near Shipka, Bulgaria, and dates back to the middle of the 4th century BCE. This archaeological site is notable for its unique architectural design, featuring a stone entrance corridor leading to an antechamber and a rectangular chamber with a distinct covered ceiling. The ceiling transitions from a double-pitched to a semi-cylindrical design, which is characteristic of Thracian architecture. The tomb's interior is lined with large marble blocks, and it contains a ritual stone bed, indicating its use for ceremonial or funerary purposes. The presence of a stone door that locks from the inside further emphasizes its function as a secure burial chamber. The last known use of the site included the burial of a horse, reflecting the cultural practices of the Thracian people.
