Final answer:
The question refers to the evidence of a building and its location in Jerusalem, as well as the dating of pottery to a specific century BC. The specific century BC is not provided in the question.
Step-by-step explanation:
The evidence of the building being blank and its location in the oldest part of Jerusalem suggests that the question is referring to a historical site or artifact. The mention of pottery dating to a specific century BC, the time of David, further supports the historical context.
Based on the information given, the specific century BC is not stated, so it cannot be determined without further evidence or clarification.
