The Pena Palace – Sintra, Portugual – A summer residence for the Portuguese royal family built 1842-1854 by King Ferdinand and Queen Maria II – Over time the colors of the red and yellow façades faded but by the end of the 20th century the palace was repainted and the original colors restored

Had the pleasure of visiting Sintra in 2016. This place is absolutely breathtaking, and that is truly a "Castle in the sky."
