The Most Beautiful Church in the World

In 1883, whimsical creative architect Antoni Gaudi started working on Sagrada Familia (sacred family), a huge Roman Catholic church in Barcelona, Spain. At the time of his death in 1926 (he was hit by a streetcar), less than a quarter of the building was finished. Slow progress then and later was partially due to lack of funding (it relied on private donations) and the Spanish Civil war (1936-39) By 2010, when I first visited, it was more than halfway done, but the central nave was stacked with building materials so we had to walk around the edges. On my second visit, last September (2018), the interior was complete and spectacular. The outside towers, however are still under construction, and the expected finish date is 2026—100 years after Gaudi’s death.

Known as God’s Architect, Gaudi felt that the Medieval Gothic style of his day was limited. It relied on large support structures called buttresses, and he believed that God’s house should be free of bulky supports, yet limitless in its height and grandeur, so he turned to nature, or what he saw as God’s architecture. The support columns of the church resemble the stems of plants, making the design stronger and lighter and allowing for more natural light. Gaudi built many of his models upside down to show how the weight would be distributed.

The main entrance, in the nativity façade, contains a complex variety of scenes featuring Jesus, Mary, Joseph, angels, kings, shepherds, flowers, animals and birds, all depicting the adoration at the birth and life of Jesus. The rear entrance, or Passion façade, depicts the death of Jesus with simple lines and figures. Many architects have worked on the church since Gaudi’s death, and all did their best to stay true to his plans and vision. Sagrada Familia has been declared a UNESCO World Heritage site.

Leonardo da Vinci’s French Connection

flying machine

Leonardo da Vinci was a genius artist, inventor, town planner and architect. In 1516, he accepted an invitation from French King Francois I to live and work in Amboise, France. Until his death in 1519 at age 64, Da Vinci lived in Chateau du Cloux (now Clos Luce) near the royal castle, so, of course, we had to visit the house, now a museum.

Da Vinci’s inventions are displayed in miniature in the house, and full-size around the extensive grounds. Flying machines, paddle-wheel boats, revolving bridge (portable, for armies on the move), helicopter (aerial screw), machine gun, armored car (precursor to the modern tank), giant crossbow, a double-decker bridge that was supposed to help stop the spread of the plague, and his artwork hanging from trees.

We were also lucky enough to be there for a special exhibition on the progression of flying machines, from a man-powered set of wings to hot-air balloons and beyond.

India’s Ancient Magical Observatories

I wanted to climb the steps, but it was not allowed, and a guard stood by to ensure everyone followed the rules. Still, the idea of climbing on the giant edifices tugged at me just as it does a child who steps into an enchanting playground. And that’s what this place looked like—a playground filled with odd-shaped structures that begged to be climbed.

Part of the Jantar Mantar in New Delhi, India

In reality, though, we were at Jantar Mantar—an astronomical observatory built by Maharaja Sawai Jai Singh, a soldier, scholar and ruler with a lifelong interest in math and astronomy. He founded the city of Jaipur in the 1720s and built five Jantar Mantar observatories in northern India.

Jantar Mantar means “instruments for calculation,” or “magical calculations.” The Jaipur observatory consists of 18 devices for measuring time, predicting eclipses, observing planet orbits; calculating the lunar calendar and predicting the start of the monsoon season. It’s main purpose, though, seems to have been casting horoscopes, which require a precise knowledge of the positions of the sun, moon, planets and stars at the moment of birth.

The largest instrument (with steps leading to its top) is a sundial 27 meters high, its shadow carefully plotted to tell the time of day to an accuracy of about two seconds. You can see the shadow moving at 1 millimeter per second, or roughly the width of a hand (6mm) every minute.

Influenced by the Islamic school of astronomy, Jai Singh also incorporated elements of early Greek and Persian observatories into his designs. The Jantar Mantars, however, are more complex, on a greater scale, and contain some completely unique designs and functions.

They were made almost entirely of masonry, with some engraved metal rings and plates set into masonry foundations, and they were built large because the larger the scale, the more accurate the measurements. Once finished, they could not be corrected or improved, and observations were limited to those involving the positions and motions of heavenly bodies that are visible to the naked eye.

Over the years, they’ve been restored from time to time—partly because they are tourist attractions, but also to keep them useful and scientifically authentic. Local astronomers still use them to predict the weather for farmers (although the accuracy is questionable), and students of astronomy and Vedic astrology are required to take some of their lessons at the observatories.

Because of their size and inflexibility, the Jantar Mantars were obsolete even before they were constructed and were soon replaced by smaller machined brass instruments and telescopes that proved more useful and accurate. Still, they are amazing reminders of ancient innovation and man’s quest to understand the universe.

Cee’s Fun Photo Challenge: Bridges

Dragon Bridge, Da Nang, Vietnam

Dragon Bridge, Da Nang, Vietnam

Rong Gao (Dragon Bridge), Da Nang, Vietnam. Built in 2013 and designed by U.S. engineers, this dragon breathes fire and hissing smoke (water mist) each weekend after sunset. Now that I’ve photographed it during the day, returning at night is on my Bucket List.
