Regal Pena Palace in Sintra, Portugal

Overlooking the lush Sintra Mountainside under a clear blue sky is the magnificent Pena Palace—a masterpiece of Romanticist architecture. Its eclectic mix of styles includes Moorish Revival, Renaissance revival, Gothic revival, Neo-Romanesque, and Manueline elements that stand out against its vibrant yellow façade. A series of ornate battlements line the rooftop terrace where visitors are seen enjoying panoramic views while others ascend the grand staircase to explore further. Vibrant bougainvillea flowers add splashes of color at the foreground, complementing this historic site declared as a World Heritage Site by UNESCO.
