The yellow customs house sits on the lawn between Fort Christiansvaern and the Scale House.  When merchants passed through the scale house, their next stop was the Customs House where they would pay taxes.  This building was made with a mix of European and island style.  The graceful 16-step staircase was a typical Danish feature, but the green hurricane shutters were added to protect the building from hurricane damage.  The Customs House dates back to 1734 when it was a single-story bookkeepers’ residence.  The second story was added, along with other renovations, in 1830.
