« Fretensis Maryland »— Official motto of the State of Maryland, adopted in 1951
Your quest for the "Secret Oath" begins in Annapolis, in front of the Maryland State House, a National Historic Landmark built between 1772 and 1779. This edifice, the third oldest government building in continuous use in the United States, was the scene of George Washington's resignation as commander-in-chief of the Continental Army on December 23, 1783. Its 17.7-meter wooden dome, copper-covered in 1875, dominates the Colonial Annapolis Historic District. The Governor of Maryland still presides here, marking the historical starting point of many foundational events that shaped the republic.
Right in front of the Annapolis State House, you discover the Equestrian Statue of George Washington, sculpted by Antoine-Louis Busti in 1795-1796. It is the first public equestrian statue of Washington in the United States, erected in 1796 with funding from the State of Maryland. Washington is depicted in a general's uniform, on a rearing horse measuring approximately 3.7 meters in total height. This monument was a silent witness to Washington's resignation in 1783, symbolizing the birth of the republic and the ideal of Cincinnatus, the citizen-soldier returning to civilian life.
Your journey then leads you to the Old Treasury Building, a two-story Georgian brick building, listed on the U.S. National Register of Historic Places in 1971. Built in 1735 as a tobacco warehouse, it was converted into Maryland's treasury in 1769, storing colonial and state funds until 1843. Restored in 1987, it now houses government offices and embodies the financial management of the young nation. Nearby, you can see St. Anne's Church, whose steeple, added in 1869, is visible 1.5 km around the State House, recalling the presence of Maryland's first settlers as early as 1695.
Continue towards the William Paca House & Garden, the residence built in 1765 by William Paca, a signer of the Declaration of Independence (1740-1799). The 2-acre formal garden, restored according to original plans from the 1760s, was designated a National Historic Site in 1971. Located approximately 0.8 km from the Maryland State House, this property is furnished with colonial-era artifacts and has offered guided tours since 1975. It represents the life of the elites who shaped the history of Annapolis and the Maryland Historic District.
Your exploration culminates at City Dock, Annapolis's historic port since 1649, which was a colonial commercial center with wooden wharves. It was here, 1 km from the State House, that the Continental Congress ship arrived in 1783. Restored in the 1980s, it still hosts annual festivals like the Boat Show since 1970. A short walk away, Reynolds Tavern, built in 1747, hosted George Washington in 1783-1784. This thematic circuit in Annapolis will have allowed you to grasp the essence of Maryland's heritage, from its republican foundations to the living places of its heroes.
