Located in the Mediterranean Sea are a set of Spanish islands known as the Balearic Islands. One of those island, Menorca, is home to an impressive collection of megalithic stone monuments called the taulas.
The origin and purpose of the taulas is unknown, although they are the works of prehistoric humans. There have been several theories surrounding the mystery of the taulas, generally focused on religious or astronomical purposes. Some believe they are a religious symbol. Others claim the taulas served as a temple of healing. Finally, there is a theory that the taulas were aligned with the movements of the moon.
