WASHINGTON — Smithsonian Enterprises, the business arm of the popular museum complex, is launching its first new magazine in 30 years with a focus on cultural travelers.

Smithsonian Journeys will hit newsstands April 21 as a quarterly publication, the publisher said Friday. Each edition will focus on one destination with photography and stories about history, food, customs and science.

The first edition is dedicated to Paris with stories about its history, the origins of the croissant and other topics, said Editor-in-Chief Victoria Pope, who previously edited National Geographic and U.S. News and World Report. Like the Smithsonian museums, the travel magazine will include some science, art and a lot of history, she said.

“I don’t think there’s anything like it,” Pope said. “We’re really combining some qualities of long-form writing with some consumer pieces that are very good with stuff about resources, what to do.”

The new quarterly will launch with a distribution of more than 150,000. Copies will sell for $13.99 each. It will be available at supermarkets, book stores, airports and on some cruise lines.
