Rising Solstice Sun shines through a big house in Murambi Suburb in Mutare .
Early in the morning on June 21st, as a result of a fortuitous combination of circumstances, the rising post-solstice Sun was captured shining through from a rear to a front window in what is known as the Blue Roof Mansion in Murambi East. This reminded me of how it rises above the Heel Stone of the famous Stonehenge monument during the summer solstice in the United Kingdom.
