Every year, at the summer solstice, the Sun reaches its maximum declination above the horizon, giving the Northern Hemisphere its longest day and shortest night. This astronomical event has fascinated human societies since ancient times, becoming a source of celebrations, rituals, and observations linked to the cycle of nature and the passing of the seasons.
In the southwest of the Iberian Peninsula, during the Chalcolithic period, many communities that built megalithic monuments paid special attention to the movements of the Sun. Numerous dolmens and collective burial sites were oriented toward specific points on the horizon associated with sunrise, particularly around the solstices and equinoxes.
These orientations do not appear to be random, but rather the result of careful observation of the sky and a symbolic conception in which landscape, astronomy, and spirituality were all part of the same reality. Even today, when the first rays of dawn illuminate the corridors of some of these ancient monuments, it is impossible not to feel a connection with those peoples who, more than four thousand years ago, gazed upon the same sunrise and found in it an expression of the order of the world and the continuity of life.
For RV travelers who are passionate about archaeology, Andalusia offers an exceptional route for discovering some of the most fascinating megalithic monuments in Western Europe.

Choose a dolmen and watch as the sunrise aligns with its passageway. Each monument “faces” a different point on the horizon: the light travels through the passageway and illuminates the chamber, just as it did more than 4,000 years ago.

Dolmen de Soto: Huelva's Great Sun Temple
Located in Trigueros, the Dolmen de Soto is one of the most spectacular megalithic monuments in Western Europe. Its long passageway, formed by enormous orthostats decorated with prehistoric engravings, faces the rising sun. On certain dates throughout the year, light slowly penetrates the interior of the monument and gradually illuminates the burial chamber—an experience that helps one understand the importance the movement of the stars held for these communities.
El Pozuelo: one of the largest megalithic sites in Andalusia
Deep in the Sierra de Huelva lies the El Pozuelo dolmen complex, consisting of several groups of funerary monuments scattered throughout the area. Its strategic location within the landscape and the orientations observed in some of the tombs reflect the close relationship between the builders of these megalithic structures and the celestial cycles. A visit here offers a glimpse into one of the most fascinating archaeological landscapes in southern Spain.
El Casullo: Observing the Solstice Four Thousand Years Ago
The El Casullo dolmen, in Berrocal, is one of the most interesting examples of solar orientation in Huelva’s megalithic culture. An alignment has been noted that corresponds with the sunrise around the time of the summer solstice, reinforcing the idea that these communities carefully observed the sky and its cycles. Its spectacular location also offers magnificent views of the surrounding mountainous landscape.
Los Gabrieles: Archaeology Amid Mediterranean Forests
Less well-known than other archaeological sites in Huelva, Los Gabrieles preserves remains that demonstrate the importance of its orientation toward the rising sun. A visit here allows you to discover an archaeological heritage that is off the beaten path and enjoy a landscape dominated by Mediterranean forests and rolling hills. It is a highly recommended stop for those who wish to delve deeper into the archaeological riches of the southwestern Iberian Peninsula.
Alberite Dolmen: A Prehistoric Gem in Cádiz
Located in Villamartín, the Alberite Dolmen is one of the oldest megalithic monuments in Western Europe (dating from around 4200–4000 B.C.). Its passageway, oriented toward the sunrise, and the engravings and paintings preserved on numerous orthostats—suns, geometric motifs, and schematic representations—demonstrate the high level of knowledge and symbolism achieved by these communities. A visit here offers a unique opportunity to see one of the finest examples of Cadiz’s megalithic heritage.
The Dolmens of Antequera: A Glimpse into the Prehistoric Sky
Designated a UNESCO World Heritage Site, the Antequera Dolmens Site comprises three monuments—Menga, Viera, and El Romeral—and serves as a veritable catalog of orientations, as each megalith faces a different direction.
The Menga Dolmen is the star of the summer solstice. It is a unique case in all of European megalithic architecture: instead of facing the rising sun, it points northeast (about 45°), toward the Peña de los Enamorados, whose silhouette resembles a sleeping face gazing at the sky. At the break of dawn on the summer solstice, the morning light streams through its passageway and falls to the back of the chamber, reaching the seventh orthostat.
Next to it, the Viera Dolmen provides a striking contrast: its passageway, oriented with extraordinary precision toward the east, is aligned with the sunrise on the equinoxes. Visiting both sites on the same trip allows you to understand, firsthand, how these communities read the calendar on the horizon.
A perfect route for RV travelers who are passionate about archaeology
What makes this route so fascinating is that it combines three elements that many travelers love: monuments dating back more than 4,000 years, spectacular landscapes in the southwestern part of the peninsula, and the freedom to discover them while traveling in a motorhome.
From the great burial corridors of Huelva to the monuments of Antequera and the exceptional Alberite Dolmen, each stop offers a deeper understanding of how our ancestors observed the sky and made sense of the world around them.
This summer solstice could be the perfect excuse to embark on a unique journey: following the path of the Sun through some of Andalusia’s most impressive megalithic monuments, using the Association’s partner sites as your base. Because, even though more than four thousand years have passed, we’re still moved by the same sunrise.
Frequently Asked Questions
Which dolmen in Andalusia is illuminated on the summer solstice?
The Menga Dolmen, in Antequera (Málaga). Unlike most dolmens, it is not oriented toward the sunrise, but rather toward the northeast (about 45°), toward the Peña de los Enamorados. At sunrise around the summer solstice, light streams through its passageway to the back of the chamber.
How many monuments are included in this megalithic route, and which provinces does it pass through?
It comprises six sites in three provinces: the Dolmen de Soto, El Pozuelo, El Casullo, and Los Gabrieles (Huelva); the Dolmen de Alberite (Cádiz); and the Antequera Dolmen Site—Menga and Viera—(Málaga).
What is the difference between Menga's and Viera's approaches?
Although they are part of the same cluster in Antequera, they point to different points on the horizon: Menga faces northeast and is associated with the summer solstice, while Viera faces precisely east and aligns with the sunrise on the equinoxes.
Where can you spend the night in a motorhome while traveling this route?
The Association’s partner sites provide a convenient base: Camper Park Playas de Luz (Huelva) for the dolmens of Huelva, the Caños de Meca site (Cádiz) for Alberite, and the Ronda Motorhome Park (Málaga) for Antequera.
Why doesn't the sun rise exactly in the east on the summer solstice?
Because on the summer solstice, the Sun reaches its maximum declination. In the southwestern part of the peninsula (about 37° N), the Sun rises at an azimuth of about 60° (northeast); at the equinoxes, it rises in the east (90°), and at the winter solstice, it rises in the southeast (120°).
Can you visit the Antequera Dolmens?
Yes. The Antequera Dolmens Site is a publicly managed archaeological complex designated as a UNESCO World Heritage Site. It’s a good idea to check the official website for updated visiting hours and conditions before you go.
