Ancient Israel is a little early for the majority of the SCA, but how often do we get to discuss a nearly three-millennia-old archaeological find? The story linked above discusses temple ruins discovered near Jerusalem as part of preparations for highway construction! Israeli archaeologists date the ruins to the 8th Century BCE, around the time of King Hezekiah of Judah and the Prophet Isaiah.
Note: I originally came across this story via a Yahoo! article, but chose to link to the Israeli government website because I found the original press release more informative.
