Always an eye catcher. White walls and red tiled roofs stacked on the hillside.
A few months ago I was visiting Lisbon on a short business trip and on my free evening hiked up to the Castelo de S. Jorge to see the city from above and watch the sunset. It has nice open view to the west and across the Rio Tajo in Almada the Cristo de Rei monument is very striking with the colorful sunset background. See slightly different interpretation on my Instagram feed.
