"The Spanish Synagogue Is The Most Recent Synagogue In The Prague Jewish Town"
"Built in 1868 for the local Reform congregation on the site of the 12th-century Altschul, which was the oldest synagogue in the Prague ghetto.
It was called the Spanish Synagogue for its impressive Moorish interior design, influenced by the famous Alhambra. The building was designed by Josef Niklas and Jan Bělský, the remarkable interior (from 1882–83) by Antonín Baum and Bedřich Münzberger."
Considering they still work... why we making stupid ones now? The vertical design is mich safer and more efficient than the pinwheel.
