History: Travel to Sarmizegetusa Traiana and Regia - A piece of History Of Romania
Today you can travel to Romania without leaving your seat! 
Ulpia Traiana Sarmizegetusa was the capital of the roman province of Dacia. Situated in the northern part of the Roman Empire, but still in operational area of its armies it was situated in the Balkans and close to the Carpathian Mountain Ark, providing a good defense and great visibility.
The colony of Ulpia Traiana was established after the conquest in 106 CE of the area from the local residents, the Dacians, a people of Thracian descent, whose own capital was a mere 40 km away.
It was named after the Marcus Ulpius Nerva Traianus, the roman emperor of the time, one of the most successful and abile leaders of the Roman Empire
Geology: Saturn - Unique planet with a ring system
Although it wasn't posted with the tag of geology, I think it fits here nicely. If you want a break from our boulder in space you can get lost in Saturn's geology by reading 
Planet No. 6 of the solar system, No. 2 in size and mass after Jupiter and the only one with a ring system visible from our planet. Its name comes from the Roman god Saturn.
It is part of the so-called outer or gaseous planets. The most characteristic aspect of Saturn are its bright rings. Before the invention of the telescope, Saturn was the furthest from known planets and, at first glance, did not seem bright or interesting.
Geography: Google Earth pearls #10: A sliding disaster
Today's post features a big avalanche, called 'The West Salt Creek landslide'. In 2014, a massive mass of ground start sliding down until it stopped 4.5 km further. The enormous avalanche moved almost 30 million cubic meters of mud, ground and debris. On the way down it destroyed roads and irrigation ditches and killed three persons. The cause of this massive disaster was the reactivation of an old antic sliding surface which was triggered, causing the enormous avalanche. The debris flow did blocked the local river, creating a temporal lake for two years (sadly, this is not visible on the picture). The landslide acted as a dam until the lake had grown too much and breached through the dam. This caused a flood which only caused some minor damage at roads and houses downstream.
