 In this work we will talk about the roman and
arabian traces in Portugal, more specifically in the
structures used to capture and use water.
Introduction

3.  The Romans left in Portugal, bridges, theaters, dams, aqueducts, villages
... some of these Roman monuments still stand, and are impressive
testimonies of the advanced techniques of construction of this people.
The Roman Bridge of Trajan in Chaves, for example, was used for
automobile traffic until 20 years ago, despite having a respectable 2000
years of age.
 In chronological terms, the oldest of the aqueducts that are disclosed in
Portugal, is the Roman of Conímbriga of century I d.C.

 The Romans left aqueducts. An aqueduct is a canal
or gallery, underground or surface, and built for the
purpose of conducting water. Aqueducts are usually
built on arcades or under platforms of
communication routes.

 The Romans also left us bridges. Well I think we all
know what bridges are, but for those who do not
know what they are: the bridges are a construction
that allows to connect at the same level non
accessible points separated by rivers, valleys, or
other natural or artificial obstacles.

 And finally, the Romans also left us dams which are
constructions made to contain and regulate a
watercourse, allowing the formation of a water
reservoir that can be used for various purposes

7.  1. Roman Dam of Our Lady of the Dam
 Classified as "Property of Public Interest" in 1997, the
"Roman Dam of Our Lady of the Dam" was built to retain the
rainwater and the sources located in the immediate vicinity,
with a view to its use in the various agricultural works
carried out in the current zone Vila Ruiva.

 2. Roman bridge of Ribeira de Odivelas
 The Roman bridge of Vila Ruiva, on the Ribeira de Odivelas,
has a probable date of its construction, first century BC but
there are vestiges of reconstruction and additions, executed by
the peoples that followed the Roman occupation, as Visigoths
and Arabs. It is one of the most monumental Roman bridges in
Portugal, 120 meters long, about five meters wide and also
about five meters high.

9.  3. Ruins of Conímbriga
 Populated since prehistoric times, the site of Conímbriga was occupied by Roman
troops in 139 BC. C., becoming then the prosperous capital of the province of
Lusitânia. In the following century, during the rule of Emperor Augustus, the city
grew urbanistically, dating from that time the construction of structures
fundamental to the everyday life of a Roman city, such as the forum, the
amphitheater and the thermal baths. Later, a three-nave basilica was built in the
center of the village. However, the domestic architecture of Conímbriga, which
developed and renewed mainly between the last years of the first century and the
beginning of the third century, is notable for the construction of insulae and
sumptuous domus. The charm of Conímbriga lies precisely in these houses, which
keep in the stone the memories of the splendor of other times.

10.  The Picota A simple and rough wooden plant, existing 5000
years ago, other sources claim to be of Roman origin, which
served to draw water from the shallow wells or valleys,
rivers and streams, for irrigation. The pillory or stork is a
device to raise water that, until very recently, was used
from north to south of the country. Today, there are still
some, essentially in wells, with little or no use, that still
resist the popular motorbike.

11.  The Nora
 Nora is a mill or device to draw water from wells or cisterns.
It is constituted by a wheel with small reservoirs or buckets in
which the sugar mill is all uncovered and the animal works in
a circle around the nora, usually clockwise, although that of
our fifth turns in the opposite direction. The water drawers
are fixed and circular instruments used to capture the water
from the subsoil and later to be used in irrigated crops.

12. 
 The levada
 Levada is the name given to an irrigation channel or
aqueduct flanked by a pedestrian path. They are also
called the channels, usually smaller ones, that carry
water to the water mills

14. 
 As you could see, although the Roman and Arabian
civilizations have already left Portugal for centuries
and we can still find traces of their presence across
the country
