South Italy Castles and Coastal Towers


The History of Coastal Towers goes hand in hand the political and military evolution of the Kingdom of Naples. Fortifications were built in Southern Italy over and eight-hundred-year period from the 9th to the 17th centuries. The original towers were cylindrical in shape, tall and with small windows. Their main function was to sound the alarm when pirate ships were sighted through the lightning of fires, allowing the local population to find shelter into the hills and grottoes inland from the coast.
Increased Raids during the 16th Century led to Development of More Complex Coastal Defenses
Naples Viceroy Don Pedro of Toledo ordered the construction of massive, square-shaped towers with thicker external walls. The transition from circular-shaped towers to square-shaped ones was spurred by the introduction of artillery requiring fortifications whose functions now included sighting, signaling, shelter as well as the use of offensive weapons that could hit a ship approaching the coast.
Communications were carried out through a series of visual signals - smoke in the daytime, fires by night as well as acoustic signals such as bells, or shots from a cannon or arquebus, a precursor of the rifle. When a pirate ship was sighted from one tower, one of these signals would be used to warn the people of the area to prepare to fight or flee. The signal would be passed from tower to tower, up and down the coast, passing the word quickly and effectively. The ground level floor had no windows and was set directly above a large cistern to guarantee a constant water supply. This space was used to store food and munitions and also contained a millstone for grinding wheat, making the tower self-sufficient.
Saracen Towers can be viewed along the Southern Italian coastline from Gaeta to the Sorrento peninsula, the Amalfi and Cilento coasts. There are over 350 towers, including 30 along the coastal strip from Vietri sul Mare to Positano. Some have been restored and incorporated into modern buildings in small harbors such as San Marco, Pisciotta and Marina di Camerota. Further south, around Cape Infreschi just before reaching Scario, there are cliffs along the coast unreachable by road; here the original coastal towers stand just a few hundred yards apart.
The Term Saracen has shifted over time. Ptolemy's Geography from the second century mentions Sarakene as a region in the northern Sinai Peninsula and refers to a people called the Sarakenoi. For Italians during the middle ages it meant Muslim invader, from the Arabs who rode the initial wave of Islamic expansion into Spain and Sicily in the 8th and 9thcenturies to the Ottoman Turks who took Constantinople in the 15th century.
Coastal Watchtowers were also as a point of reference for friendly ships. The towers were generally manned by a military team of four guards and a horseman, who often remained outside the tower ready to ride into town to carry a warning as soon as possible.

Development Projects Impact Assessment

points of reference
Traffic Safety and Congestion getting through the nearest signalized intersections in one green cycle during rush hour conditions. Standing at each proposed new intersection location, verify visibility of approaching vehicles at the minimum, safe sight-distance formula: posted speed limit + 10 mph x 11 feet/mph. Example: 30 mph + 10 = 40 x 11 = 440 feet sight - distance. Trips generated by the project on neighborhood streets are below 2,000 vehicles per day.
Safe Streets and School Overcrowding for residential areas, can the additional students resulting from the project be accommodated without exceeding the capacity of affected schools. Sidewalks are adequate to allow students to safely walk or bike to school along the streets receiving traffic from the project.
Trees and Forests complying with tree canopy or forest conservation laws.
clustered homes maximize forest preservation
Buffering and Screening of commercial and industrial projects from the view of adjacent residential homes. If the project obstructs natural views from existing homes, then the proposed landscaping must
be sufficient to preserve views.
Property Values commercial or industrial structures to be at least 300 feet from residential homes. If the project is commercial-industrial, can trucks reach the site without travelling on residential streets.
Air Quality if the project is a gas station, it must be at least 500 feet from homes, hospitals, schools, senior centers and day care facilities. The homes must be 500 feet from a highway with traffic volumes of 50,000 or more vehicles per day.
Fire and Emergency Medical Services the project must be within a four to eight-minute response time for fire and emergency medical services. In suburban-urban areas with water pressure sufficient to meet fire suppression needs.
Recreation Areas for residential projects, a minimum of 10 acres of park or other recreation areas for every 1,000 residents is recommended. For suburban-urban residential projects, there should be a neighborhood park within a ¼ mile walking distance of the site.
Water Supply for projects served by wells, verify the likelihood that area wells fail or become contaminated. If the site is served by piped-public water, the project must not exceed the safe or sustainable yield.
Flooding all proposed structures must be outside the 100-year flood plain, with runoff managed to prevent an increase in floodwater elevations downstream of the site.
Historical-Archeological Resources if a designated historic-archeological resource is present on or near the site, the local historic society must ascertain that it is adequately protected. For buildings 50 years or older slated for demolition, the local historic society should be consulted about the need for protection.
Water a buffer of native vegetation undisturbed within 100 feet of streams, wetlands or other aquatic resources. Rooftops, streets, parking lots and other impervious surfaces drain to bio-retention, infiltration or other highly effective storm water system. Project sewage is sent to a treatment plant and the pipes carrying the sewage do not overflow. The treatment plant has met pollution discharge limits for the last 3 years; If the project will be served by onsite sewage disposal, site soils should be rated for Septic Tank Absorption Fields in accordance with USDA Web Soil Survey.

The Rapid City South Dakota Commercial Historic District

The Black Hills area became important as a commercial center for transient miners in the 1870s, but later served the needs of more stable social-economic groups. The district's structures are of late 19th and early 20th century origin and reflect typical period architecture. Rapid City was founded with the idea that it would be a service center for people and materials destined for the gold fields. John R. Brennan persuaded a group of unsuccessful miners to establish a town on the eastern slopes of the Black Hills where he and his followers had discovered an adequate water supply in Rapid Creek.
Rapid City was founded on February 25, 1876 and was named for the nearby stream
At first, the city failed to grow in population and economic strength despite its location on freight routes from Nebraska and eastern South Dakota. As corporate mining replaced individual prospecting, and stable homesteading and ranching elements settled the surrounding areas, Rapid City became a permanent consumer market. It soon aspired to be the wholesale center for western South Dakota and the gateway city for the Black Hills.
Better transportation was necessary to achieve commercial primacy; municipal bond sales induced the Missouri, Fremont, and Missouri Valley Railroad to enter the city on July 4, 1886 creating new business opportunities and a quadrupling of the population between 1880-1890. Three additional railroads followed the Missouri, Fremont, and Missouri Valley and contributed to the economic security of the region.
Commercial success was manifested in the historic district's architecture. Rapid City's earliest buildings normally consisted of non-descript frame structures. Prosperity soon stimulated more elaborate construction consisting of brick, cut stone, and limestone. Italianate, Neoclassical, and Renaissance designs dominated throughout the district. The period architecture and historical importance of these buildings create an impressive historic district.
The characteristics of the buildings create the appearance of a late 19th and early 20th century city
The Rapid City Historic Commercial District consists of thirty-eight buildings in the center of the town's business area. This district includes one complete rectangular block and portions of five others. Most structures are two stories, along with one and three-story structures. A single eight story building towers over the district. All roof tops are flat and usually are covered with tar. Although roofing materials are similar, exterior wall coverings vary. Most buildings are brick of different color, texture, and shape. Limestone, cut stone, clapboard, stucco, and modern siding are used in the facing.
512 6th Street - 1911 this structure was one of the three main buildings in the district used for professional offices. The building was built by the Elks for a meeting hall. It is of the Neoclassical type and is three stories high. Brick and masonry are the main facing materials used. The building features pilasters, dentils, brackets, cresting and masonry ornamentations.
601 Main - 1916 a two-story structure of Neoclassical design situated at the corner of 6th and Main Streets. This building is the Pennington County Bank and is constructed of limestone. The building has always been a bank and reflects the district's commercial importance.
610 Main - 1915 this structure still houses a fire station; one of few such fire stations left from this era. It is a two-story brick veneered building with masonry materials used as decorative features It still has the fire house doors and the only alteration has been the addition of another vehicle door on the west side.
523 6th Street - 1927 an eight-story structure and one of the earliest tall buildings in the state. It has served as a hotel throughout its existence. It is constructed of brick facing with masonry as decoration.
