Thingvellir is a national park where the Althing – an open-air assembly, which represented the whole of Iceland – was established in 930 and continued to meet until 1798. The Althing has deep historical and symbolic associations for the people of Iceland. The property includes the Thingvellir National Park and the remains of the Althing itself: fragments of around 50 booths built from turf and stone. This false-colour image uses primarily information from the near infrared part of the spectrum in order to emphasise differences in vegetation. Near the centre of the image is Lake Thingvallavatn, whose water surface appears black because water absorbs infrared radiation almost entirely. The image was recorded by a satellite of the Landsat series, which has been used for over 30 years for Earth observation, thereby making possible identification of long-term environmental changes.

The image was taken on 16 August 1995 by the satellite Landsat-7 / ETM+ and has a resolution of 30 metres. It covers an area of 80 by 160 kilometres.
