Saqqara is one of the most important heritage sites in Egypt and the world. Many foreign missions have been operating there for a long time. The French mission is one of the oldest missions working in Saqqara. In 2014, under the supervision of Prof. Philippe Collombert, the mission pursued the excavation of the Shawaf site, which is to the north and east of Queen Behenu's pyramid. At the entrance of the complex, they found some stone blocks and several offering tables. One of the offering tables may possibly be dated back to the Herakleopolitan Period. It was very fragile and needed to be cleaned. For security reasons, the offering table was transported to the storeroom, where conservation and restoration works were completed.
