A more thorough explanation:

Hostilaria

A hostilaria is a place or room in a religious house that is used to welcome and accommodate guests and strangers. It is also known as hospitalaria.

• When the weary travelers arrived at the monastery, they were directed to the hostilaria where they were given food and a place to rest.
• The nuns who lived in the convent were responsible for managing the hostilaria and ensuring that guests were well taken care of.

These examples show how a hostilaria is a place where guests and strangers can find refuge and hospitality in a religious setting. It is a place where they can rest, eat, and receive care and attention from the religious community.
