a well, fountain, or other source of drinking water or a place of refreshment/entertainment, such as an inn, tavern, or festhall,
a shrine, temple, or other religious site,
a bazaar or khanduq or an administrative/government building for the town or city,
a service building, such as smithies or guildhouses,
