S elf-taught Swiss-American photographer Alex Teuscher traveled to the temples of the old city of Angkor in Cambodia to capture the beauty of a bygone age. These sites of worship were first established by the Hindu monarchy in the 9th century, only to be transformed into Buddhist temples in the 12th century, before another Hindu restoration later in that century, as the dominant religion changed. Eventually the Khmer Empire withered, but the ruins are still out there. The most famous is Angkor Wat, but the last city discovered by archaeologists, Mahendraparvata, was uncovered in 2013. These sites draw in the faithful and tourists today.
