MAGNETOMETER SURVEY ON A ROMAN AGE AREA AT THE TOWN OF ESTE (VENETO REGION)

The survey was committed by  the local municipal authority because the area was destined   to    Cemetery   enlargement.   Since a lot of archaeological material were found on the surface, it was decided to verify  the  presence   of  archaeological structures.   Of  course   the decision about the enlargement of the Cemetery was subordinated to the results of the magnetometer survey.

Looking at the contour map of magnetic anomalies, a 100 m long and 30 m wide complex anomaly is visible; it is composed by two intense parallel  magnetic   alignments  and  by  a   less  intense   arc  shaped anomaly.   Ther   alignments  are  probably  produced by boulders of trachyte usually used  in Roman  age to build roads and to defend the embankments. The perimetrical walls of a building and the remains of the flooring in  the   north-east  corner  of  the  map  (pointed out with arrows), are also visible.

A MAGNETOMETER SURVEY ON A PALEOVENETIAN AREA AT THE TOWN OF ESTE (VENETO REGION )

A magnetometer survey  was  conducted  on  an area considered of archaeological interest where some buildings were planned.     In the magnetic contour map, the presence of many anomalies variable both in shape  and   amplitude  is  visible.     In order to verify the structure responsible of the  magnetic  anomaly  A B,  two trenches were dug orthogonally to them;  in  both  of them an embankment 1 meter deep came to light. On the top of the dyke there was a pavement 10 meter wide, made by little calcareous chips; boulders of intrusive magmatic rock were found on the bottom of the trenches. The other anomaly C D  was  excavated  too,  revealing   the  existence  of a wall built with boulders of trachyte. The initial building plan was then changed, and buildings  were  erected  in  the   part  of  the  area  free  of magnetic anomalies.

MAGNETOMETER SURVEY AT ALTINO ( VENICE )

At  Altino, an archaeological   site    near  to  Venice, ARCHAEOSURVEY conducted its largest magnetic survey.  The global result   is  shown  in   form  of  shaded  relief map :    the town planning, with buildings organized in districts delimited by roads and channels like in the city of   Venice  can be recognized.    Among the features, it is   worthy  to  mention  the one, very probably a channel crossing the center of the area in   south east - north west   direction. On both sides of this structure, in particularly on the right one, a serie of linear anomalies (roads)   approximately  22 meters each to other, oriented in north east - south west direction can be seen. On the left border of the map, another linear anomaly with the same direction of the channel, is easily   recognizable.     Looking  through the map, it is evident the presence    of at least two kinds of anomalies; besides the linear anomalies some   tens  of  large  and  strong  anomalies  can be seen.      Probably  some  of these  anomalies are caused by kilns or furnaces, their  shape  and   the very    strong intensity would seem to guaranter this deduction.

MAGNETOMETER SURVEY CARRIED OUT AT CAMPAGNA LUPIA (VENICE)

The result of the magnetic survey can be considered  exceptional;  in the south west sector of the map a building with the dimensions of 46 m x 30 m is clearly visibile. On both the short walls of the   building, it is possible   to perceive two small square cells 8 x 8 meters;  another structure 60 meters long and 14 meters wide orientated north south is recognizable.   At last, another   structure is  visible on the north east corner.  In the east sector   of the map  the most    important   result is represented  by   the picture   of a building  60  meter long oriented  in north-south direction. Inside the structure there is another building  of square  shape, approximately 13x13 meters. Like the building  of  the south west sector, the structure presents two small cells on  the  north and  south sides  and a   corridor; in this case inner walls   look  better preserved than the   outer ones. The archaeological  excavation of the south west sector confirming the results obtained  by  the survey. The excavation brougth to light the trachyte  foundations of a temple.
