11 incredible places to celebrate the spring equinox in 2023

Humans have marked the spring equinox for millennia. A time of symbolic rebirth, its arrival in the Northern Hemisphere on March 20 signifies warmer days and the start of crop preparation, as well as holding religious significance for many.

This equinox is one of only two days a year when the sun crosses the celestial equator, meaning that both day and night last 12 hours (the September equinox being the other). In anticipation of the event, people throughout history have built sites that align with the springtime sun. Some erected vast stones that wouldn’t cast a shadow during the equinox, whilst others built tombs that would only reveal their secrets when illuminated on the day.

Here are 11 incredible sites to experience the transition from the doldrums of winter to the freshness of springtime during 2023’s spring equinox.

1. El Castillo, Mexico

As the largest Mayan temple in the pre-Columbian city of Chichén Itzá, El Castillo (The Pyramid of Kukulkán) rises some 98ft-high (30m) above Mexico’s Yucatán jungle. During the spring and fall equinoxes, a shadow slithers along the edge of one set of stairs, creating a 120ft-long (36.6m) body of a snake whose head is carved in stone at the bottom. It’s believed that this display is in honor of the feathered serpent god Kukulkán, who would grant its worshippers health and a good harvest.

2. Stonehenge, England

Hauled and dragged for more than 150 miles from Pembrokeshire’s Preseli Hills in Wales, the giant slabs of rock that make up Britain’s most embolic stone circle still attract thousands of curious visitors each year.

Erected during the neolithic period, you can’t enter the inner grounds of this special, celestial spot for much of the year in order to protect it. However, during the equinoxes and solstices, hundreds are allowed into Stonehenge to celebrate the sunrise. Its bright beams carefully align with the sarsen stones at the center of the site and line up with the movements of the sun as druids, pagans, Wiccans, and drummers welcome the new dawn with a rhapsodic cacophony.

3. Chaco Canyon, United States

Located in New Mexico’s remote Four Corners region, Chaco Canyon National Historical Park houses a collection of massive structures dating to 850 CE that are considered to be the religious and governmental center of the Ancestral Puebloan world.

Several of the buildings mark significant astronomical events, the most impressive of which is Casa Rinconada, a large hilltop kiva (ceremonial and social chamber). During the spring equinox, the sun climbs the walls and shines through two aligned doorways and into a small niche in the wall.

4. Spiro Mounds, United States

Spiro Mounds Archaeological Center is an 80-acre site in rural Oklahoma near the Arkansas River that was a major political and religious meeting place for the Northern Caddoan Mississippian people between 700 and 1500 CE. 

Large earthen mounds were burial chambers for those of high status, with remains and artifacts recovered during the 1930s excavations. On the spring equinox, the sun rises directly behind Mound No. 2 when standing at the main temple.

5. Angkor Wat, Cambodia

Built in the 12th century as a Hindu temple city and later dedicated to Buddhism, the 402-acre Angkor Wat temple complex is the world’s largest religious site. At dawn on the spring equinox, the sun rises directly behind its 65m-high center tower and casts the entire temple in silhouette against the lightening sky.

6. Carrowmore Megalithic Cemetery, Ireland

Located near Sligo town on the Cúil Íorra Peninsula, Carrowmore Megalithic Cemetery is Ireland’s largest megalithic cemetery. Visitors can explore more than 35 passage tombs, many of which are nearly 6000 years old. During the spring equinox, the sun rises from behind a saddle in the Ox Mountains and illuminates the tombs which are oriented to the equinoxes.

7. Mnajdra, Malta

Mnajdra, a megalithic temple built circa 3600 BCE, sees the morning sun of the spring equinox shine directly through the main entrance down the length of the site and into a recessed shrine. This happens during the fall equinox as well, with sunlight during the solstices falling to the left or right of the shrine through the perfectly-angled placement of the entrance corridor.

8. Teotihuacán, Mexico

At the Palace of Quetzalpapálotl in Teotihuacán, Mexico’s biggest ancient city and likely capital of the country’s largest pre-Hispanic empire, the morning equinox light casts a shadow that travels up a feature depicting solar and lunar symbols, such as owls.

However, this isn’t what attracts thousands of onlookers. Many arrive here to climb the Pirámide del Sol (Pyramid of the Sun) and bathe in the sunlight which some believe will give them energy for the year.

9. Cromlech of the Almendres, Portugal

Cromlech of the Almedres consists of two stone circles and more than 95 granite boulders that date to 6000 BCE, making it among the oldest known megalithic sites in the world – thousands of years older than Stonehenge. 

Situated on an east-facing hill slope 9 miles west of Évora, on the morning of the spring equinox the sun rises along the axis of the monument, casting in-line shadows of the stones.

10. Basilica San Petronio, Italy

Basilica San Petronio in Bologna is not just Europe’s sixth-largest church, but also one of the world’s largest solar observatories. This 14th-century Gothic structure houses Cassini’s Meridian Line, a 219ft, brass and copper rail in the floor of the church’s left aisle. It was inlaid by astronomer Giovanni Cassini in 1655. A one-inch hole in the ceiling 88ft above allows a ray of sunlight through, and every day at noon sunlight hits the line somewhere along its length, depending on the time of year. 

At noon of the spring equinox, the light perfectly hits its mark on the floor. Considering that Easter falls on the first Sunday after the first full moon following the spring equinox, it was important to know exactly when the spring equinox took place. This served a religious purpose but turning the cathedral into a solar observatory also greatly contributed to science.
