The Macelum in Pompeii is an excellent example of a Roman fish market. The circular area would have had a domed roof which would have had a hole in the top of it to allow the smell of the fish to escape (something modern fish markets could do with!)
The Macellum (in English, market) was the covered market of the grocerieses. It was built in the Samnite Period and turned into the actual aspect in halves the first century. To the entry you can see a kiosk with Corinthian columns and an arcade under which there were the shops of the money-changer.
The macellum has got a rectangular shape (37*27 meters); the interior walls were decorated: on the west wall you can see great frescos with black background and red bands containing pictures of mythological subject. You can recognize Io guarded by Argus Panoptes, Ulysses and Penelope; aloft you can see a frieze with fishes, birds and amphoras. On the south side there are rests of shops. In the middle of the courtyard there was a circular structure with the foundations of 12 columns.
pictured is the forum of pompeii. the forum was the center of economic, political, and religious life in the city. in the forum is the ruins of the basilica, built between 120 and 78 BC it was the oldest public building in pompeii. the columns in the right of the picture is the portico of the macellum. the macellum was a collection of large buildings that was a shopping area. also housed in the macellum was statues of octavia, (the sister of augustus caesar), and marcellus. (the nephew of augustus). these statues are now on display in the museo archeologico nazionale in naples.
This area is directly adjacent to the Forum. This area served as a large market. Wine and fish were two of the most common products sold here. The central area was likely used as a display area for fish, while other shops surrounded the area. There were a couple of casts of victims displayed here when we visited.
The Macellum, situated at the far end of the forum, was the covered fish and meat market of Pompei. Glad there was no fish now - it would have stunk to high heaven!
A covered part can still be admired
The Macellum was a market. It had an open area in the centre in which there was a circular building which contained a pool of water. The remains of this can be seen in the picture. This pool most probably contained fish which could be bought. Around the edge of the Macellum were shops or 'tabernae'. At the back of the building there was a shrine dedicated to members of the Imperial family.
Here in the Center You Can see 12 bases Which were used to support a wooden roof under Which a fountain was provided for cleaning the fish sold in the market
