Custom house
government office building for import and export of goods
A custom house or customs house was traditionally a building housing the offices for a jurisdictional government whose officials oversaw the functions associated with importing and exporting goods into and out of a country, such as collecting customs duty on imported goods. A custom house was typically located in a seaport or in a city on a major river, with access to an ocean. These cities acted as ports of entry into a country.
Due to advances in electronic information systems, the increased volume of international trade, and the introduction of air travel, custom houses have largely become obsolete. Many custom houses around the world have since been converted for other uses, such as museums or civic buildings.
As examples, the former Alexander Hamilton U.S. Custom House in Manhattan, New York, (now the George Gustav Heye Center) presently houses a branch of the National Museum of the American Indian, the former U.S. Custom House in New Orleans, Louisiana, is now home to the Audubon Butterfly Garden and Insectarium, the former U.S. Custom House in San Francisco, California, now houses offices of the U.S. Customs and Border Protection and Social Security Administration and the former U.S. Custom House in Baltimore, Maryland, was in 1973 serving as a Selective Service office. As of 2019, the Custom House of Valletta in Malta was still being used for its original purpose.
History
Custom Houses became a prominent feature of English ports after 1275, following the creation of a national system for collecting duties on overseas trade.
In the United Kingdom, since 1386, the phrase "custom house" has been in use over the term "customs house". This was after the City of London's Custom House was erected at Wool Wharf in Tower Ward, to house just the officials overseeing the Great Custom on Wool and Woolfells.
“Custom house” enters the record as government office building for import and export of goods. Crown Archives preserves that source wording while asking what Custom, house and government can confirm, complicate or overturn.
Why this record matters
“Custom house” is worth following because a concise public description often conceals a longer documentary argument. Here, Custom, house and government provides the most credible route into that argument.
Place names and jurisdictional language are key evidence: both can reveal earlier catalogue descriptions and overlooked record series. The source revision retrieved here is dated Nov 27, 2025. The linked authority identifier is Q218653. The Library of Congress control number is sh88004487. None of the 1 selected statements returned an explicit reference. The first chronological checks are 1973, 2019, 1275 and 1386.
Architectural summaries often privilege surviving fabric and can understate demolished phases, contested use or displaced communities. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
