June 2017

When the dictator Rafael Trujillo ordered the construction of the monument pictured in our April 2017 mystery photo, the Monument to the Heroes of the Restoration — located on a hill in the city of Santiago de los Caballeros, or simply Santiago, in the Dominican Republic — he intended the structure to honor only himself. That was in 1944. After his assassination in 1961, the country's government changed the structure's name from Trujillo's Monument to Peace; to its current name.

Each year, the European Tree of the Year competition elicits votes from the public to name Europe’s best tree. 2017’s winner is the 650-year-old Oak Józef, in Wis´niowa, Poland, which two Jewish brothers hid in during WWII and which was once depicted on the 100-złoty bill. For descriptions, histories and GPS coordinates of the 2017 candidates and former winners, visit www.treeoftheyear.org.

South Downs National Park, just south of London, England, was granted Dark Sky Reserve status in 2016 by the International Dark Sky Association (http://darksky.org), a nonprofit group that seeks to protect areas of excellent night-sky viewing from pollution by light. 

To qualify for this status, the Snowdonia National Parks Authority made assurances to reduce or eliminate artificial light. Light pollution cannot be completely eliminated in the park, as there are some villages within its boundaries.
