Grindul Lupilor area is located in the Southern part of the reservation having the same name, it has a surface of 2,075 hectares, being neighbored by Zmeica lake in the North-Western part, by Sinoe Lake in the Eastern, Southern and South-Western parts, by Channel 2 in the Western part and by Golovita lake in the Northern part.
The aquatic environment is predominant, from here arising the less ordinary character of the flora and fauna, which have adapted to this environment. The terrestrial environment is represented by sand banks, droughty areas in which grow a flora and fauna specific for the East - European steppes with Mediterranean influences.
Between these two environments (aquatic and terrestrial) it is interposed the swampy easily flooded area, bearer of a flora and fauna with possibility of alternative adaptation (water, land), depending on the hydrological conditions, seasonal and yearly. The area represents an important shelter for nesting and nourishment for about 300 species of birds. Especially during fall migration, the area becomes an impressing concentration of ornitofauna and, especially, of the winter guests.
Grindul Lupilor is the sanctuary of some natural curiosities which confer it, in certain places, the aspect of a real tropical jungle. The underground water is near surface, fact which favours the formation of a humid soil. The forests are disposed in narrow strips called "hasmacuri" (in Turkish language).
Advanced bulwark of Greek culture and civilization and furthermore of Latin culture, Dobrudja represents - through its antique monuments - a museum itself, and the micro-region Grindul Lupilor (Wolves Sand Bank), represents perhaps, the most fabulous and attractive window of this museum, the result of one-century researches of Romanian archaeologists.
Here, on the shore of Sinoe Lake, there lays Histria citadel, the first Greek colony on the Western shore of Pontus Euxinus and the oldest city on the territory of our country. As a toponym, Histria derives from Istros, the Greek name of Danube river, the city being located at '500 stadia far from the sacred spring of Istros', upon the notices of antique historian and geographer Strabon, on the sea shore. Set up in the middle of VIIth century b. Chr. by the colonists from Milet, Histria had a continuous development from the Greek period until the end of Roman period (beginning of VIIth century a. Chr.), justified by the favorable conditions of fishing, agricultural land and easy ways of communication with inland, the city being for a long time the most important economic and cultural center of our region
The tourist visiting Grindul Lupilor (Wolves Sand Bank) pension must know that at only 10 km South from Sinoe village, can be visited the beautiful and impressive citadel and the modern museum of Histria, in which he will discover the charm and grace of an era long gone. Here there can be seen the material proofs of existence of human communities in the area since paleolithic (35000-10000 b.Chr.). There can be admired also in the glass cases of the museum tools and ceramic receptacles from Aeneolithic and Bronze eras, discovered on the territory of current villages Sinoe, Mihai Viteazu, Cheia, Istria-Sat, Gura Dobrogei, Cogealac, Corbu.
Upon the end of Bronze Era and in the first Iron Era (XIIth - Vth centuries b.Chr.) in Dobrudja, so also in the region of Sinoe lagoon, there is developed a characteristic culture, firstly Thracian and then Getic, autochthonous, which will interact with the Greek colonists in the VIIth century b. Chr. Histria will be raised in the middle of native Thracian-Getic population, as a colony having tight commercial, cultural and religious relationship with the Southern world, as proved by the ceramic receptacles manufactured in Milet, Atena, Rhodos and Corinth, and discovered here. The temples and inscriptions dedicated to Zeus, Afrodita, the Muses, Dionissos or to Apollo are proofs of rich spiritual lives of the Histrians.
Starting with Ist century a.Chr. Histria will pass through a new period of development, the nowadays territory of Dobrudja being integrated into the Roman State. The thermal baths, the precincts and most of the buildings that can be admired nowadays in the citadel pertain to this period. An epigraphic document issued by the governor Laberius Maximus, in year 100 a.Chr., was mentioning the borders and the rights of the citadel - the center of the Histrian economic life consisted in cultivation of agricultural land and in fishing.
Inside the territory controlled by the citadel there was also vicus Quintionis, a village developed on the property of a Roman colonist, Quintio, located on the territory of present village of Sinoe. The inhabitants of the antique village from Sinoe were "veterani et cives Romani et Bessi consistentes", as reminded by an inscription from IInd century a.Chr., meaning veterans and Roman citizens together with bessi, Thracian population brought by the Roman state from the Balkans. The heads of the village were two magisters, chosen by the inhabitants from the wealthy persons. The inscriptions are presenting the names of some mayors as: Tiberius Saturninus and Bizienis, from year 144 a.Chr., Aelius Bellicus and Mucaporus Ditugenti from year 167 a.Chr., Iulius Florus and Derzenus Bitti from year 177 a.Chr. a.s.o.. There can be observed the good fellowship and the yearly character of the mayor position (magister vici), one being elected from the veterans and roman citizens and the other one from Thracian community.
For the financial part of antique city from Sinoe, the mayors were assisted by a quaestor, chosen by alternation, one year from the Romans and one year from bessi. For instance, in year 167 a. Chr., quaestor was Claudius Ianuarius, and in year 175 a.Chr. a Thracian Dotus Zinebti.
In vicus Quintionis there was an auditorium - hall of audience and trial - mentioned in an inscription from the times of emperor Antoninus Pius.
The aerial photographs showed the existence of some roads that were connecting the village to Histria city and to the settlements from Fantanele, Mihai Viteazu or Istria. Furthermore, like in the case of other rural cities from Roman epoque, the village from Sinoe was provided with water brought through aqueduct.
The Roman settlement from nowadays territory of Sinoe ceased its existence in the same time with Histria citadel, sometimes at the beginning of VIIth a.Chr., as proven by a coin from Heraclius (613-614 a.Chr.), once with desertion of entire Dobrudjan territory by the Roman army.
The ones going to Grindul Lupilor (Wolves Sand Bank) will be able to observe nowadays the beauty of antique world inside Histria Museum and to watch piously the funerary piles of the antique people, inhabitants of these lands, all integrated in the wild landscape from the lagoon.
