閉館

1. Origins, structure, and basic meaning

• Structure: 閉館 (へいかん) is an event noun for a facility ending operations and closing, also used with する.
• Basic usage: 美術館は閉館する predicates the facility’s scheduled closing, while 閉館の放送 specifies the event announced over the public-address system.

2. Common pitfalls and similar expressions

• Daily closing versus permanent closure
  • 午後六時に閉館する and the 閉館の放送 prompting visitors to leave concern the day’s end of operations. These examples do not establish permanent closure of the institution.
