This is the treasure room in the basement of the Portugese Synagogue in Amsterdam. The collection includes 43 pairs of silver and gilded ornamental towers which are placed on top of the Torah scrolls.
They are fabricated by late seventeenth and eighteenth century Dutch silversmiths.
Often the pinnacles are decorated with coats of arms and monograms referring to the donors.
Here an example of the Torah scrolls with the ornaments on top.
