The agreement between the Town of Santa Marinella , the Marconi Radioeletric Centre and the Italia AIR FORCE has been confirmed for historical Marconi site at "Torre Chiaruccia".
The Mayor Roberto Bacheca opened the ceremony, in the magnificent scenery of the Castle of Santa Severa, of the conference "From the researches of Guglielmo Marconi on microwaves to the future - the voice of the Pope", organized by the City of Santa Marinella, Guest Star Princess Elettra Marconi, sponsored by CARICIV Bank an the Patronage of the Senate of the Itale Republic, Lazio Region, Italian Air Force, CNR National Research Centre and RAI TV, Msgr. Dario Edoardo Viganò - Prefect for the Communication of the Vatican City, CReSM Marconi Radioelectric Centre, the Logistics Command of Military Air Force, ARI Radio Amateur of Civitavecchia, Ostia and Capofigari, AMSAT Italy, Italian Naval League, Italian Marcon Stations, Fundación Titanic of San Sebastian (Spain), LAZIOcrea and CoopCulture.
Maurizio Gasparri - Vice President of the Senate, chaired the Conference organized by Professor Livio Spinelli, delegate of the Mayor for "Science Park Guglielmo Marconi - Air Force". 
The lectures wereheld by the Commander of the Logistic Command of Italian Air Force Gen. S.A. Giovanni Fantuzzi,

the Journalist. Alessandro De Carolis, head of the Vatican Cecretary of communication
and Princess Elettra Marconi, honorary citizen of Santa Marinella.
Marconi first in the world in 1930 established in Santa Marinella at "Torre Chiaruccia" his Lab to research Microwaves applied to MOBILE PHONES, RADAR and TV and 1935 he inaugurated his first RADAR STATION in Santa Marinella where he had asked the company's factory in Genoa to build him a small transmitter of 50-centimetre wavelength, with a receiver to match. In April, while testing them at Torre Chiaruccia outside Rome with Luigi Solari, he bounced radio waves off his car, driven back and forth by his chauffeur, and then off a circling aircraft. At every stage, the British parent company was kept informed of these experiments.

Left the RADAR DISH atop the wooden scaffolding used to locate airforce planes flying
over the tower, ships entering the nearby harbour of Civitavecchia as well cars along the
Aurelia motorway
There seems to be no evidence that the Italian government learnt
anything from the experiments.In December 1935 the British government
asked the Marconi company to design and manufacture the transmitting
'curtain' antenna arrays for the first five 'Chain Home' radar stations,
covering the Thames Estuary and approaches to London. The transmitter
was designed by Metropolitan Vickers and the receiver and display unit
by A.C. Cossor Ltd. In May 1937 came an order for providing similar
arrays for 20 additional stations.
Without the protection given by these radar stations, the Battle of Britain three summers later would almost certainly have been lost.

DEVELOPMENT OF RADAR
Date / Dates:
1916: Marconi and Franklin note reflection of short-wave signals.
20 June 1922: New York - Marconi prophecies radar in address to American Institutes of
Electrical and Radio Engineers.
26 February 1935: Robert Watson-Watt carries out practical test with RAF bomber following
publication of his paper on aircraft 'Detection and Location - by Radio
Methods'.
15 April 1935: With Solari, Marconi conducts radar tests at Torre Chiaruccia.
December 1935: British government orders first five Chain Home radar stations covering
approaches to London and Thames Estuary;.
May 1937: British government orders 20 more CH stations; company provides 'curtain'
Antennae for all stations.
(1944: Marconi company designs, develops and manufactures 'Bagful' for recording German radio frequencies and 'Carpet', a radar jamming system used by RAF Bomber Command.
On 20 June 1922, while addressing American radio engineers in New York, Marconi forecast new types of marine radio apparatus that would project electrical waves, detect those reflected back from metallic objects, and so "immediately reveal" the presence and bearing of other ships.
Stemming from his earlier observations, his speech heralded the technology of what would later come to be called 'radio detection and ranging' or RADAR for short.
Advances made by the Marconi company in marine direction-finding helped pave the way for the development of these techniques, whilst Marconi's own work on blind navigation and microwaves was also a pre-requisite.
In Britain, during February 1935, Robert Watson-Watt of the government's Radio Research Laboratory conducted the first successful ground-to-air test involving radio detection, with an RAF bomber aircraft flying through the beam of the BBC's short-wave transmitter (built by Marconi) at Daventry.
