White Urn

Hi All my grandparents have used this urn for about 20 years and first bought it in a junk shop. It does look as if it has been in the ground at some point. They have asked me to help them to get it identified and so i was wondering if i could get some kind of identification of its age and what it would have been used for.

any markings underneath?

Storage jars/amphorae like this would have been used for liquids such as water, wine, fermented fish paste, olive oil, etc. The photo is out of focus, but possibly a Mediterranean shape. They were made in huge numbers in the Mediteranian, Africa, India, Indonesia and Mexico, and copied for sale in garden centres. Best to ask a local museum if it's an original or a copy.

This is an example from Morocco with similar added surface decoration and lug handles.
