Archaeologists have discovered a cellar dating back to the Avar Period, in 670 AD. According to my own research, the Avar Period existed within the time period known as The Great Migration, or The Dark Ages, following the fall of the Roman Empire. (Zeljko Zidaric, "The Great Migration-The Dark Ages").
The artifacts found around the cellar however, date back to the 10th and 11th centuries. It was during this time in history, that Hungary founded the state of Hungary and converted to Christianity. In 1000 AD, Hungary's first King was crowned, King Stephen. King Stephen was canonized in 1083, and is still celebrated to this day (hungary-tourism-guide.com).
The upper layers of the dig, mainly consisted of the skeletal remains of children from the 17th and 18th century, from a civilian cemetery. All skeletal remains have been taken to the Varvara county museum for further examination. In the 17th and 18th centuries, Hungary was freed from the Turks but then became apart of the Habsburg Empire in which they fought an unsuccessful war for independence from 1703-11. It was also during this time that Hungary saw a large flow of migration from Germans, Croatians, Slovakians, and Romanians (hungary-tourism-guide.com).
Digging has expanded in order to look for more underground buildings. The new digging next to the Griff Hotel, across the street from the Great Church, has revealed remnants of a fountain.
The archaeologists are calling this sight an archaeological phenomena. Unfortunately for investors however, this phenomenal find has pushed back the restoration plans for downtown. Originally, plans were to begin construction at the end of November. It now appears that the archaeological dig will continue until at least next spring.
