I recently posted a reflection of one of the buildings from the Alhambra in Granada. Not only does this beautiful collection of buildings have historical significance but also architectural.
The decorations, like this ornamental relief, within the palaces were typical of Moorish dominion within Spain. Experts (not me) will tell you that this was from the last great period of Andalusian art in Granada.
From 19th-century until the present day, many buildings and portions of buildings worldwide have been inspired by the Alhambra. There’s even some ‘copycats’ in the USA and Portugal.
All I know is that if you visit, don’t just look at the buildings but have a close look at the small intricacies such as this.
