Solomon's Temple was the first temple of the Jewish religion, constructed in Jerusalem circa 1000 BCE, and destroyed by the Babylonians circa 586 BCE.
The biblical Book of Kings 1 gives detailed descriptions of the construction of the Temple.
At 1 Kings 7:23 it gives the following description of the measurements of the "molten sea", a large round laver which the Temple Priests (the "kohanim") used for washing of their hands prior to performing their duties.
"He made a molten sea of ten cubits from brim to brim, round in compass,and five cubits in height thereof, and aline thirty cubits did copass it around about."
This would equate to a value of pi = 3 for construction purposes.
