Every Catholic knows that the Blessed Sacrament is reserved in a special safe, known as a tabernacle, typically on or behind the main altar of the church (or, in greater churces, in a splendid side chapel). Actually the word "tabernacle" means "tent" and comses from the veil with which it is covered
It's helpful to remember that there have traditionally been other methods of reserving the Sacrament. The Lion and the Cardinal has a photo post on the Eucharistic Dove -- reserving the Sacrament within a gilt dove which is suspended within a silver.
