The first word at the bottom left in cursive on this postcard certainly looks like Bingvellir. However, an online search shows that it is actually Þingvellir, using the correct Icelandic character Þ.  In English it’s written as Thingvellir. This postcard shows Almannagjá Canyon at present-day Thingvellir National Park. The area has great historical, cultural and geological significance, and Thingvellir National Park is on UNESCO’s world heritage list. At Thingvellir, the Alþing (Althing in English) an open air assembly that represents all of Iceland, was established in the year 930 and continued to meet there until 1798. The park was designated as a protected area by a special law passed by the Alþing on May 7, 1928, and is one of Iceland’s most frequently visited places. Geologically, the area is described as part of a fissure zone running through Iceland, and situated on tectonic plate boundaries. Thingvellir is part of the North Atlantic Rift, and is one of the few places in the world where two major plates can be observed to be drifting apart.

This postcard is the second one posted on this website with credits on the back showing for Hans Petersen, who was possibly the photographer.

Divided back, deckled edge, unused postcard. Einkarjettur. Hans Petersen, Reykjavík. Stamp box shows the number series 402751. Date unknown, possibly circa 1910-1930.
