Dr. Antonio M. Wilson, theological researcher and author, has participated in archaeological research alongside the Institute of Archaeology of the Hebrew University of Jerusalem. While collaborating with the institute, Dr. Antonio M. Wilson worked at the Ophel City Walls site, a complex of buildings dating back nearly three millennia.
The Ophel City Walls archaeological site is one of the oldest archaeological finds in Israel, and visitors can now walk through many of the remains of the site. Conservation work began in 2010 after the fortification complex was completely exposed. Some of the remaining architecture includes a royal edifice, a possible gate house, and a section of the city wall.
Many significant artifacts have been found at the Ophel City Walls site. For example, clay jars that would have contained wine or oil were found in a partially destroyed building. One of the jars has an engraving that indicates it was owned by a kingdom minister. The crown jewel of the excavation, however, is the earliest written document found thus far in Jerusalem. This tablet fragment consists of a handful of words written in Akkadian cuneiform script.
