Medici Marble Lion


One of a pair of copies of the Carrara marble Medici lions, these lions guard the bridge that connects St. Augustine, Florida to Anastasia Island along historic A1A in Florida. The lions were made by Romanelli Studios in Florence, Italy. Other copies of these lions include the famous ones displayed in the Throne Room of the Royal Palace of Madrid. The Bridge of Lions is listed on the National Register of Historic Places and is considered by the National Trust for Historic Preservation (NTHP) fragile, added to the 1997 “11 Most Endangered Sites” list.


The Medici lion statues were copies of the statues at Loggia dei Lanzi in Florence, Italy, and were gifted to the town by resident, Dr. Andrew Anderson, who also built and lived at the National Register historic mansion, Markland House, now owned by Flagler College. In the later years of Anderson’s life, he installed a number of works of art in public places. The lions were his last artwork gift to St. Augustine, and he had smaller versions made for his home.

Spanish Bronze Cannon


Bronze cannon at the Castillo de San Marcos National Monument in St. Augustine, Florida, laser scanned with Artec Spider. This beautifully designed cannon is covered in a rich green patina. Bronze was preferred because it could withstand the stress of firing better than other materials. In coastal Florida, an added benefit is that bronze can withstand dampness and is non-rusting with nearly two times the life expectancy of an iron cannon. Less metal material is required to make a weapon, and bronze could be melted down and recast into a new weapon, as needed. This cannon can be found on display in the courtyear area. the cannon is an 18-pounder bronze weapon from Seville. It dates to 1764, and is named El Milanes (The one from Milan). The piece is on loan to the Castiilo since 1971.

Historic Seawall



This is a portion of the historic seawall at the Castillo de San Marcos (aka Fort Marion). The view is to show the seawall that fronts the fortification, with the model shown as a plan view section. The full height of the fort is not shown in this section, with the fort wall provided to show location in relation to the seawall and water battery locations.

Hot Shot Furnace


The hot shot furnace is part of a water battery, built between 1835 and 1844, located on the east side of the Castillo de San Marcos National Monument in St. Augustine, Florida. This furnace would have been stoked by a team of soldiers preparing cannonballs as “hot shot” that would be used to fire at incoming wooden ships. The shot was ready after about 30 minutes of heating in a coal bed. Metal tongs were required to remove the shot and prepare it for firing from the cannon and artillery stationed nearby along the fort’s seawall.


Although not a technique that was battle proven at the Castillo, soldiers did routinely drill for the possibility of using hotshot to fend off invaders. This technology went out of vogue when ironclad ships came into use and made these type of furnaces obsolete. Background image is courtesy National Park Service, c. 1939 from the publication: Hot Shot Furnaces (pg. 6).

The Americans brought the fort’s defenses up to date by thickening the seawall, filling in this section of the moat, and building granite and iron semi-circular gun platforms. ### Title album_0941E169_32F3_2443_41C1_9AF994AF3254.label = Photo Album _D859284 album_3F12AA05_3121_EFEF_41C3_4C070FD1B8F7.label = Seawall Photos map_380CF412_7942_38CC_41C9_CA2A75711CCF.label = PointcloudSeawall2 panorama_097241AB_224E_1916_41BB_2D7C8C1AFE6F.label = Moat panorama_0974C73E_224E_196F_419D_C522DECEE264.label = Seawall panorama_09A0FC1A_22C2_0F04_41C2_B7A030014648.label = Seawall panorama_09A1C4C3_22C2_FF0B_41B9_374846FEA2FA.label = Seawall panorama_09A1D261_22C2_3B04_41C4_A3EBA448F09C.label = Seawall panorama_09A1E742_22C2_3904_41B0_E8E90B49FEF9.label = Seawall panorama_09A6BAC7_2246_0B10_41B5_F24E6005FC32.label = Artillery panorama_09A6E3B3_2246_1971_417F_1064ABFA1ACA.label = Artillery panorama_09A74255_2246_3B31_41C5_15D1CA854ED2.label = Artillery panorama_09A78E79_2246_0BF1_41B9_F68D114A9D5B.label = Artillery panorama_09A7B5CB_2246_7910_41C0_BA86CF9D2DBE.label = Artillery panorama_0B9B48C9_22C2_3707_41C1_AB6F3E6721B9.label = Seawall panorama_6533D62A_2246_3AD5_4187_195BF0DA7D46.label = Seawall panorama_683145F3_79CA_6301_41AD_F3E582986BA4.label = Seawall panorama_6860466D_79C9_E101_41A9_6BE6AD79A4BF.label = Seawall panorama_6B2F0660_79FE_613F_41BF_26E4A652AA1C.label = Seawall panorama_6FCCDB0C_22CE_0AFF_41A6_48F5B876423A.label = Seawall panorama_7609A446_79D9_A103_416A_3FEA0800CCD0.label = Seawall panorama_ED713B58_E3D7_A32B_41C3_50D95D5BB7E3.label = Seawall panorama_F1F01D68_E4BD_A725_41D9_9AF9FCD157FE.label = Artillery panorama_F1F91E61_E4B5_6558_41C2_B9C409C5B146.label = Moat panorama_F1F92284_E4B5_9DDF_41BC_60FAD6598547.label = Glacis panorama_F1F99A5E_E4B4_AD68_41B5_6002D922B951.label = Seawall panorama_F1F9D086_E4B4_BDD8_41D4_ED12C698A616.label = Moat and Drawbridges panorama_F1FA9B6B_E4B7_A32F_41D5_2539AD2D6091.label = Seawall panorama_F1FAC7F2_E4B7_E339_41CD_6FC223FDE47A.label = SeaWall panorama_F1FAF470_E4B7_A539_41D8_55B62A92B3B6.label = Moat panorama_F1FCF940_E4BC_AF64_41C8_D6896E3C7174.label = Hotshot Furnace panorama_F1FDA1C4_E4BD_7F6D_41E0_A4154375B07C.label = Hotshot Furnace panorama_F1FEB459_E4BC_A567_41E4_577C9D19F3BB.label = Hotshot Furnace panorama_F1FF4F15_E4BF_64E2_41E6_4584209DDBA7.label = Seawall panorama_F1FFD7DB_E4BC_E31A_41DC_D54F68D81C48.label = Hotshot Furnace panorama_F204D580_E4B3_67E5_41BB_0B118DFAFD15.label = American Modifications video_43FF4216_7AC2_3EFC_41AA_8E55CDA235AB.label = SeawallLoadingVid ##
