18. Conclusion The astronomical heritage from Mesopotamia is a tangible moveable heritage, namely cuneiform tablets containing astronomical texts No tangible immovable heritage is known; for example, no buildings have been identified as astronomical observatories or site There are also many monuments in the area that their astronomical usage are not recorded, but could be suggested from observation and estimation The more recent observatories, towers,… are also available ( probably partly or mostly destroyed) which are well documented
