The most impressive archeological site in Mallorca, in my opinion, is the Poblat Talaiòtic de Ses Païsses, near Artà. Archeology in Mallorca mostly refers to the Talaiotic period, in this case to the time of approximately 1300 B. C., which was well before the Romans arrived.
The impressive Ses Païsses site was excavated by an Italian, would you believe it, a certain Giovanne Lilliu, between 1959 and 1963. That’s not all that long ago.
The site is closed at the moment until January 8th, 2008, and will then be open for your visit Monday to Friday, 09h00 to 13h00 and 14h00 to 17h00. The Talaiot is sadly not accessible on Saturdays, Sundays or public holidays.
