The uprights of the House of Taga are about 16 feet tall. There are twelve latte here in 2 rows of 6. Four were for corners, and the rest were for support along the length of the building which rested on the top. These stones were quarried by hand and transported about a mile or so from Taga Beach. Chamorro were utilizing latte construction around 1100 AD, and apparently still had some latte buildings at the time of Spanish discovery in the 1600's. Apparently only the higher caste could live in latte houses. Commoners had wooden huts built on the ground. I have never seen an authoritative date for when House of Taga was built, but I assume it was sometime between 1100 and 1600.
I have also never heard nor read an authoritative account for how the stones were put into place. How the cap stones were placed on top is, to me at least, quite a mystery.
