In the 2005 was excavated the area between Tumulus 9 and Appendix 2, known as the Appendix 1. This Appendix was near by the Tumulus 9, thus for it was considered as part of this Tumulus. Five graves have been found in Appendix 1, dated to the Classical and the Early Hellenistic periods, showing that very probably these platforms are what is left of another tumulus completely destroyed. The graves are all simple pits and inhumations. The skeletons are placed in a supine position, with extended arms and legs.
Two graves are dated to the Classical/Early Hellenistic period by stratigraphy, orientation (approximately towards south), and date of grave goods. The rest is dated very likely to the post-Medieval period by stratigraphy, orientation (towards west), and absence of grave goods. All these elements correspond with what has been observed in Tumulus 9. The majority of the grave goods is represented by black-glazed vessels and metal objects such as pins.
