Maresha was an Iron Age city mentioned in the Hebrew Bible, whose remains have been excavated at Tell Sandahanna (Arabic name), an archaeological mound or 'tell' renamed after its identification to Tel Maresha (Hebrew: תל מראשה). The ancient Judahite city became Idumaean after the fall of Judah in 586 BCE, and after Alexander's conquest of the region in 332 BCE became Hellenised under the name Marisa or Marissa. The tell is situated in Israel's Shephelah region, i.e. in the foothills of the Judaean Mountains, about 1.5 kilometres (0.93 mi) south of Beit Gubrin.

Excavations revealed that Maresha was inhabited (not necessarily continuously) during the Iron Age, the Persian period, and the Hellenistic period. The Hasmonean ruler John Hyrcanus seized Maresha in 113/112 BCE, leading to its decline and eventual desertion. The city faced its ultimate destruction at the hands of the Parthians in 40 BCE.

Maresha was first excavated in 1898–1900 by the British archaeologists Bliss and Macalister on behalf of the Palestine Exploration Fund (PEF) and again after 1989 by Israeli archaeologist Amos Kloner on behalf of the Israel Antiquities Authority (IAA). Most of the artifacts of the British excavation are to be found today in the Istanbul Archaeology Museums.

This site is now protected as part of Beit Guvrin-Maresha National Park and its burial caves are recognized by UNESCO as a World Heritage Site.

The location of Maresha in relation to Eleutheropolis (Beit Gubrin) has been noted by Eusebius in his Onomasticon, who wrote:

Maresa (Joshua 15:44). Tribe of Judah. It is now a deserted site about 2 milestones from Eleutheropolis.

C.R. Conder and H.H. Kitchener of the Palestine Exploration Fund surmised that Maresha should be identified with Khurbet Mar'ash, a ruin 3⁄4 mile south of Beit Jibrin, based on a phonetic similarity of their names. It was not until J. P. Peters and Hermann Thiersch explored the ruins of Khurbet Sandahannah (grid position 140111 PAL) in 1902 that they discovered a Greek funerary inscription in an adjacent burial cave (known as the Sidonian burial Cave) which explicitly identified the site as Maresha. Today, Khurbet Sandahannah is an archaeological tell comprising 24 dunams (5.9 acres), with its "lower city" incorporating into it an additional 400 dunams (98 acres).

Maresha was one of the cities of Judah during the time of the First Temple and is mentioned as part of the inheritance of the biblical tribe of Judah in the Book of Joshua.

Later, in the second Book of Chronicles, it is named as one of King Rehoboam's fifteen fortified cities. In 2 Chronicles it is the site of a battle against an invading Ethiopian army.

According to the Madaba Map, Maresha was the place "whence came Micah the Prophet". In the 6th century BCE, as result of Zedekiah's rebellion against the Babylonian kingdom and its king Nebuchadnezzar II, the latter occupied the Judean kingdom and sent many of its inhabitants into exile. This marked the end of Maresha as a Judahite city.

Following these events, Edomites who had lived east and south of the Dead Sea migrated to the area and Maresha emerged as a major Idumean city. Hence, from the Persian rule and throughout the Hellenistic kingdoms' rule in the region (6th – 1st century BCE), Maresha was part of the area known as Idumea, a Hellenised form of Edom. During the period of Persian rule, Phoenician colonies were encouraged to spread out along the coastal regions of Palestine and in the adjacent hill country of Judea, whence their early settlement in Maresha took its rise.

With the conquest of the region by Alexander the Great the city was settled by retired Greek soldiers as was then custom. Thus Maresha reached its zenith, developing as a Hellenistic city encompassing a multitude of Greek and oriental cultures including Sidonians and Nabataeans. With the advent of Hellenisation, the settlement pattern changed, as most everywhere in the region, and the city expanded far beyond the constraints of the fortified, raised tell or mound of Iron Age Maresha. Maresha became the center of an administrative district in the Ptolemaic empire, while from 200 BCE onward the center of a Seleucid administrative district.

The city began its decline during the Maccabean Revolt against the Seleucid Empire (2nd century BCE) when the city was used as base to combat the rebels. The Book of Maccabees reports that Judas Maccabeus and his forces marched through Marisa in around 163/2 BCE when the city was burnt during Judas' conquest of the Idumaean region, from Hebron to Azotus (Ashdod).

Following the rebellion and its success, John Hyrcanus conquered the city in c. 112 BCE, forcibly converting its inhabitants to Judaism.

In 63 BCE, as part of the arrangements made by Pompey in the region, Maresha, along with all of Edom, was separated from the Jewish kingdom and returned to Idumea. In 47 BCE Julius Caesar then annexed the city to Judea.

Maresha was finally destroyed in 40 BCE by the Parthians as part of the power struggle between Antigonus of the Hasmoneans who had sought their aid and Herod, who was a son of the converted Antipater the Idumaean and was being supported by the Romans.

It remains unclear where the city of Marissa was located after Hyrkanus captured it and apparently forbade its inhabitants from living in the upper city, where a garrison was stationed. Very meager remains from the time up to 40 BCE were found in one corner of the upper city, and almost none in the large lower city surrounding it, which once covered an area of 320 dunams. If indeed neither the upper nor the lower city were reinhabited at least in part, the one remaining possibility mentioned by Amos Cloner is that the name of Maresha was transferred to the nearby hill of Bet Guvrin, which could have been used as the main settlement of the district for several decades, from the end of the second century BCE until its destruction by the Parthians. A first-century BCE coin, presumed to have been minted by the citizens of Maresha, was discovered during excavations at Bet Guvrin, which can be interpreted as an argument in favour of this suggestion.

After the demise of Maresha, the neighbouring Idumean/Jewish town of Beth Gabra or Beit Guvrin succeeded it as the main settlement in the area. Shaken by two successive and disastrous Jewish revolts against Roman rule in the 1st and 2nd centuries, the town recovered its importance only at the beginning of the 3rd century when it was re-established as a Roman city under the new name of Eleutheropolis. By the time of Eusebius of Caesarea (d. 340 CE), Maresha itself was already a deserted place: he mentions the city in his Onomasticon, saying that it was at a distance of "two milestones from Eleutheropolis".

The Palestinian Arab village Bayt Jibrin, standing on the site of ancient Eleutheropolis, was depopulated during the 1948 Arab-Israeli war. In 1949 Kibbutz Beit Guvrin was established on part of Bayt Jibrin's lands. Most of the archaeologically important areas of ancient Maresha and Beit Guvrin/Eleutheropolis are now part of the Beit Guvrin-Maresha National Park.

Archaeological excavations have been conducted at the site from 1972 to 2002 by Amos Kloner and from 2002 until 2014, by Bernie Alpert and Ian Stern, initially on behalf of the Archaeological Seminars Institute and the Israel Antiquities Authority (IAA). From 2014 excavation and publication work continued on behalf of the Nelson Glueck School of Biblical Archaeology of Hebrew Union College-Jewish Institute of Religion. Less than 10 percent of the caves surrounding Tel Maresha have been excavated. Located some 400 meters above sea level, the bedrock is soft chalk, lending itself to the hewing of caves which were used as quarries, cisterns, tombs, animal mangers, olive presses and dovecots (columbaria). Many of the caves are linked by an underground maze of passageways.

During excavations at Tel Maresha, archaeologists uncovered a lead weight with a Greek inscription that read: "Year 170 (corresponding to 143/2 BCE), the agoranomos [= "market inspector"] being Antipater, son of Heliodorus, and Aristodamus, son of Ariston (?)." The calendar year is written according to the Seleucid era counting, during which same year Simon Thassi of the Hasmonean dynasty assumed power.

Among the major archaeological finds at this site is the Heliodorus Stele. This stele recounts events in Judaea prior to the Maccabean revolt and offers important historical evidence for events that would precede events which modern day Jews commemorate during the holiday of Chanukah.

Approximately 500 ostraca were found in Tell Maresha alone, 400 of which discovered since 2000. Included among these are both dated and undated dockets, tags with personal names and a number of letters of correspondence.

In 2022, a large number of knucklebones were found. Some were used to play games (for example, knucklebones) and others to contact the gods (astragalomancy). Those that bear writing were in Greek.

Today Maresha is part of the Israeli national park of Beit Guvrin. Many of the ancient city's olive presses, columbaria and water cisterns can still be seen. Furthermore, the Archaeological Seminars Institute, under the license of the Israel Antiquities Authority, conducts excavations of Maresha's many quarried systems, and invites visitors to participate.
