There is no and there can not be an universal tag for “marriage place”, since in different countries, cultures and religions it happens in different places. Even within a single country and culture there can be diverse options. For example, in Russia marriage ceremony can be held at general register office, at dedicated civil facility in presence of registrar officer or there can be religious ceremony held at church. All these places are different entities.
marriage in Iran “marriage registration office” is performed in the presence of representative Registration Office. The marriage registration office like a law office and only records the marriage.
