Every synagogue contains an Ark, which is a cupboard where the Torah Scrolls, which contain the text of the Hebrew Bible, are kept, and a desk from which to read the Torah.
The Hebrew words of the Ten Commandments are usually written somewhere above the ark.
The Ark is named after the wooden chest which held the stone tablets of the Covenant that God gave to Moses on Mount Sinai.
The search for that original Ark formed the plot of the movie Raiders Of The Lost Ark.
