In Pula (Croatia) can be found the base of a Roman octagonal mausoleum from the 1st-2nd century CE. Archaeologists believe that there was a tomb in its central part, and the entire octagonal structure had a roof.
The mausoleum is believed to have been over nine meters high, since only the lower part is about 1.5 meters high. The mausoleum was discovered in 1941.
