In this photo of part of the University of Aberdeen, three distinct phases of building can be seen.  On the right hand side of the picture is part of the King's College Chapel which was built in 1498. The tower in the centre is the Cromwell Tower which dates from the 1650's (and is still used for its original purpose as an observatory), and the arched walkway forms part of the Elphinstone Hall, built in 1930.

Å is the last village at the end of the Lofoten islands. Population 500.

New King's Building, University of Aberdeen.  Built in 1913 to provide extra lecture room space, and designed in a style to match the five hundred year old buildings opposite (more of which on another day ......)

From the photo archive, a traditional scene from Lofoten, Norway.

I spotted this nacreous cloud low on the horizon this evening after sunset. This type of cloud is comprised of ice particles and forms at around minus 85 celsius, in the lower stratosphere.  They are quite beautiful; vivid and iridescent, and also quite rare.
