It is the fifth-most populous city in Greece with a population of 148,562 in the city proper, according to the 2021 census. It is also the capital of the Larissa regional unit. It is a principal agricultural centre and a national transport hub, linked by road and rail with the port of Volos, the cities of Thessaloniki and Athens. The municipality of Larissa has 164,095 inhabitants, while the regional unit of Larissa reached a population of 268,963 (in 2021).

Legend has it that Achilles was born here. Hippocrates, the "Father of Medicine", died here. Today, Larissa is an important commercial, transportation, educational, agricultural and industrial centre of Greece. The city straddles the Pineios river and N.-NE. of the city are the Mount Olympus and Mount Kissavos.

The Thessalian plain (Greek: Θεσσαλική πεδιάδα, Θεσσαλικός κάμπος) is the dominant geographical feature of the Greek region of Thessaly.

The plain is formed by the Pineios River and its tributaries and is surrounded by mountains: the Pindus mountain range to the west, which separates Thessaly from Epirus; Mount Othrys and its outliers in the south; Mount Pelion to the east; Mount Ossa and Mount Olympus to the northeast, with the pass of the Tempe Valley leading to Macedonia; and the Chasia and Kamvounia mountains to the north.

Anciently, Magnesia (Ancient Greek: Μαγνησία) was a region of Ancient Greece, eventually absorbed by ancient Thessaly. Originally inhabited by the Magnetes (Μάγνητες), Magnesia was the long and narrow slip of country between Mounts Ossa and Pelion on the west and the sea on the east, and extending from the mouth of the Peneius on the north to the Pagasaean Gulf on the south. The Magnetes were members of the Amphictyonic League, and were settled in this district in the Homeric times, and mentioned in the Iliad. The Thessalian Magnetes are said to have founded the Asiatic cities of Magnesia ad Sipylum and Magnesia on the Maeander. The towns of Magnesia were: Aesonis, Aphetae, Boebe, Casthanaea, Cercinium, Coracae, Demetrias, Eurymenae, Glaphyrae, Homole or Homolium, Iolcus, Magnesia, Meliboea, Methone, Mylae, Nelia, Olizon, Pagasae, Rhizus, Spalaethra, and Thaumacia.

The Vale of Tempe or Tembi (/ˈtɛmpi/; Greek: Τέμπη, Κοιλάδα των Τεμπών; Ancient Greek: Τέμπεα, Τέμπη) is a gorge in the Tempi municipality of northern Thessaly, Greece, located between Olympus to the north and Ossa to the south, and between the regions of Thessaly and Macedonia.

In the Greek municipality of Tempi, the valley is ten kilometers long and as narrow as 25 metres in places, with cliffs nearly 500 metres high. Through it flows the Pineios River on its way to the Aegean Sea. Historically the gorge has provided a strategic route through the mountains and its impressive rugged beauty is poetically renowned.

Eurymenae or Eurymenai (Ancient Greek: Εὐρυμεναί or Εὐρυμέναι) or Erymnae or Erymnai (Ὲρυμναί) was a town and polis (city-state) in Magnesia, ancient Thessaly, situated upon the Aegean Sea coast at the foot of Mount Ossa, between Rhizus and Myrae. Pliny the Elder relates that crowns thrown into a fountain at Eurymenae became stones. It was destroyed by Lyciscus in the 4th century BCE.

The site has been located at a place called Kokkino Nero.

Homolium or Homolion (Ancient Greek: Ὁμόλιον) or Homole (Ὁμόλη) was a town and polis (city-state) of Magnesia in ancient Thessaly, situated at the foot of Mount Homole, and near the edge of the vale of Tempe. Mt. Homole was the part of the chain of Ossa lying between Tempe and the modern village of Karitsa. Mt. Homole is sometimes used as synonymous with Ossa. It was celebrated as a favourite haunt of Pan, and as the abode of the Centaurs and the Lapithae. Pausanias describes it as the most fertile mountain in Thessaly, and well supplied with fountains.

Livy writes that during the Third Macedonian War, Perseus of Macedon encamped at Sycurium, between Mount Ossa and the lower Peneus; it overlooked the plains of Thessaly and was not far from Larissa.

Its location is near the modern village of Neromylo Agias (or Neromyli). Archaeology has revealed an acropolis with 5th century BCE fortifications and no defensive wall of the lower town.
