Located in a mountainous region east of Anditsaina the village of Theisoa was called in ancient times Lavda. Ruins of houses are found in the area, with parts of temples along with some inscriptions. The town’s acropolis is located on the northwest part of today’s community, surrounded by a strong wall. The Dutch Archeological Institute has excavated a part of a cemetery. The tombs portray an idiosyncratic style regarding the alignment of the corpses and funeral gifts.
