Baltic Latgalian tribes chose this beautiful, rich in lakes and forests area in the eastern part of Latvia for living in approx. the 1st century BC. It is proved by 14 settlements, more than 25 castle mounds and about 70 ancient burial places.
Between Small and Big Lakes of Ludza, on the top of a hill a Latgalian wooden castle was erected for protection of the borders. Around the castle an active and rich town of Ludza appeared, which received its name in honour of the castle’s owner’s daughter Lūcija.
