  The Caral civilization developed on the north-central coast of Peru and had
an occupation period between 2870 and 1970 years BC. The first studies carried
out in the field of archaeoastronomy showed evidence of possible astronomical
orientations in some buildings of its capital city, the Ciudad Sagrada de
Caral. However, methodological issues cast doubt on these conclusions. A recent
study carried out a more general statistical analysis, which covered a total of
55 architectural structures distributed in ten urban settlements that were part
of this civilization, thus managing to identify topographic and astronomical
orientation patterns. Based on this evidence, we propose to carry out a new
study focused on the capital city, with the objective of analyzing the
orientation pattern of the city, placing emphasis on the analysis of the most
important religious and administrative structures in order to determine their
functionality and their possible links with relevant astronomical objects. The
study will include field work to measure the various structures and the
subsequent statistical analysis of the data, using declination histograms,
density functions and probability tests.
