In this work we conduct a study of the orientations of 12 megalithic enclosures in the Alentejo (southern Portugal). Some of these sites date back to the sixth or fifth millennia B.C., and so are among the oldest stone enclosures in Europe. The results of the survey show a pattern of easterly (rising) orientations. In particular, we relate our results to previous studies by Michael Hoskin and colleagues, on the orientations of the seven-stone dolmens in this area, which have shown the existence of a possible sun rising orientation custom.

This paper presents a preliminary approach to the problem of royal tomb orientation in ancient Egypt from the early dynastic mausoleums at the necropolis of Umm al Qab to the impressive subterranean chambers of the tombs at the Valley of the Kings (Biban al Muluk). This clearly shows that the correct orientation of the monuments, from the earlier mastabas to the later hypogea, was mandatory and that the sky plays a key role in understanding ancient Egyptian funerary monuments.

The so-called ‘Neo-Pythagorean Basilica’ at Porta Maggiore in Rome is one of the most famous and most discussed hypogeal monuments in Rome. It was certainly in use for a short time during the first half of the first century AD, but its purpose is still far from clear. The most probable interpretation is that it was a temple dedicated to Neo-Pythagorean cults. We describe here the preliminary results of a detailed archaeoastronomical study of the Basilica undertaken in order to contribute to the understanding of the role of this fascinating monument.

The Taosi late Neolithic site is located in Shanxi Province in north-central China. Three decades of excavation have unearthed storage pits, dwellings, and many artifacts, identified as the Taosi culture type (4300 to 3900 BP). Recent excavations led to the discovery of the tombs of chiefs of the Early Taosi period, and the largest walled-town in prehistoric China. A semicircular foundation built in about 4100 BP along the southern wall was also discovered. The design of the raised terrace within it would have permitted observations of sunrise at specific dates along the eastern horizon. Here we report on what has been learned about this fascinating site, and analyze its astronomical features and function.

When tree ring dates at Mesa Verde National Park were plotted as a function of time along the lunar standstill cycle, a correlation was evident, leading to the hypothesis that architectural features and construction phases were timed according to the lunar 18.6 year cycle. A detailed architectural analysis at Sun Temple and tree ring analysis support the sub-hypothesis that lunar maximums were observed over Sun Temple from the Painted Tower area of Cliff Palace. Tree ring dates at Balcony House and Square Tower House suggest a similar relationship between construction of specialized architecture such as kivas and the lunar maximum cycle.
