Former Site of Heidenheimer's Castle

Galveston, Galveston County, Texas

Marker Inscription

In 1857 John S. Sydnor (1812-1869), former Galveston mayor, built the original two-story, eight-room structure at this site. Samson Heidenheimer (1834-1891) bought it in 1884. The German-born Heidenheimer began with a $100 loan and built a fortune as a Confederate blockade runner. He was associated with Sydnor and his son Seabrook in an auction business. Heidenheimer enlarged the house to four stories and 37 room and added castle-like tower and turrets. It changed owners many times after his death; burned in 1973, and was razed in 1975.

The Story

Former Galveston mayor John S. Sydnor built an eight-room house on this site in 1857, but it was the German immigrant Samson Heidenheimer who transformed it into a landmark. Beginning with a $100 loan and building a fortune as a Confederate blockade runner and auctioneer, Heidenheimer enlarged the house to four stories and 37 rooms, crowning it with castle-like towers and turrets. Passed through many owners after his death, the fabled 'castle' burned in 1973 and was razed two years later.

Why it matters

Heidenheimer's rise from an immigrant's small loan to a castle on the Gulf captures the go-getting, cosmopolitan spirit of 19th-century Galveston, then one of America's busiest ports.

Davidson-Penland House

Galveston, TX

Built in the years just after the Civil War by Norwegian immigrant and early Galveston settler Captain John Davidson, this house passed through a remarkable line of owners. Among them was Samuel Moore Penland, a grandnephew of Sam Houston who served in Galveston during the Civil War, became a businessman and customs official, and donated Houston artifacts and letters to the Rosenberg Library. Having survived the 1885 fire and the 1900 storm, the Greek Revival house is among the oldest of its kind in the East End district.

Pier 19, Mosquito Fleet Berth

Galveston, TX

This stretch of Galveston waterfront has carried nearly every current of Gulf history — Jean Lafitte's pirate ships, the Republic of Texas Navy, Confederate marine assaults that broke Federal occupation in 1863, and, so the story goes, Prohibition-era rum runners. In calmer years it became the berth of the Mosquito Fleet, small fishing boats named for their insect-like profiles. Their crews blended Asian and European fishing customs into a distinctly American trade, still honored in the yearly blessing of the fleet.

Levi Charles Meyers Harby

Galveston, TX

Levi Charles Myers Harby, born in South Carolina in 1793, served in the U.S. Navy during the War of 1812 and spent two years as a prisoner of war in England after his prize ship was recaptured. By 1836 he had "gone to Texas," and he later settled in Galveston, where his wife Leonora founded the first Jewish Sunday school in Texas and the city's Ladies Hebrew Benevolent Society. When the Civil War came, Harby served the Confederacy as an artillery captain aboard the CSS Neptune in the Battle of Galveston and ended the war commanding the harbor.

Trube House

Galveston, TX

Built in 1890 for John Clement Trube, a young immigrant from Kiel, Denmark, this whimsical home was styled after a Danish castle by architect Alfred Muller. Its solid brick walls, finished in Belgian cement, have weathered generation after generation of Gulf hurricanes on Galveston Island. Remarkably, the house has remained in the Trube family that first raised nine children within its towered rooms.
