Marmara Ereğlisi occupies a triangular peninsula with a ‘hook’ attached on its tip on the northern coast of the Sea of Marmara. In the past, the town was known as Perinthos and subsequently as Herakleia, out of which modern name derived. The town is locally known as Ereğli, and Marmara, although an official part of the name, serves as a disambiguator to differentiate the town from other two Ereğlis in Turkey.
Although older parts of the town resemble more of a village today, with roosters crowing here and there, during the days of Perinthos, town served as the capital of Roman province of Thrakia, and it’s hard to believe but what is today Istanbul was just a village administered from Perinthos then.
Buses operating between Istanbul and Tekirdağ (and other places west lying on this route such as Malkara, Keşan) accept passengers to Marmara Ereğlisi, but you have to get off at the junction of the highway and access road to town centre (which is not a very big deal since you can walk to town centre in about 15-20 minutes at most).
Minibuses from Tekirdağ’s otogar, recognizable by their red & white exteriors and which cost 5 TL one-way, on the other hand make it all the way to the town centre. They depart every 15 minutes daytime and 30 minutes in the evening between 6:30AM and 10:30PM and a trip takes around 50 minutes.
Despite being a coastal town, there are no scheduled ferry services to the town and quite frankly there is not somewhere suitable to anchor if you even arrive by your own boat. You may better anchor your boat in Tekirdağ and then bus the rest 40 km overland instead.
The ostentatious days of Perinthos are long gone for more than two millenia, so many of the historical sights described here are slowly vanishing. In fact many can be distinguished from natural formations only by careful eyes and only people really interested in history may find them worth of a check.
Park. There is an open-air display of marble columns and sarcophagi –as is usual in any ancient Roman site- dating back to Perinthos in a park located a few metres down the town square towards eastern waterfront. This is probably the historical sight in best condition.edit
Old town. Situated on the top of the hill rising on the tip of the peninsula, this is the oldest part of town. There are many houses around maintaining Greek architecture but most are very badly in need of a repair. One exception is Constantine’s Residence (Konstantin’in Evi), a stone two-floor mansion known by its former owner’s name. It’s situated near the western coast, a block or so down the town square. edit
City walls. Most of the old town is surrounded by ancient city walls, though in most parts they resemble more of a somewhat high garden fence rather than grandiose city walls. You may occasionally spot a (largely ruined) tower here and there if you walk around them a bit.edit
Roman breakwater. Located on the western coast, you can more easily spot it from the top of the cliff as it appears as random rocks on two straight rows lying parallel to each other when you hit to the beach next to it. Nice to watch the cormorants playing with the waves though.edit
Amphitheatre. You will not find the usual marble seats as they are covered by grass and earth several feet thick. However the amphitheatral form of half-moon ascending from a stage is still clearly distinguishable, in fact it looks more majestic with the grass and all. To get there from the town centre, walk uphill through the old town, and as you come to the edge of the cliff overlooking the sea, turn left (towards east). You’ll walk on an unpaved path for about 15-20 minutes passing beside, below and over some remnants of city walls. The amphitheatre is located right below the lighthouse on the top of the hill: Take the lighthouse (which will appear after you walked for about 5-10 min) as a bearing if it’ll make it easier for you. Don’t ask the locals about amphitheatre, they seem to be even unaware of its existence and when asked about where the tiyatro is, they show the way to the modern cultural centre which has a theatre stage. It offers a very beautiful view of the sea located below the cliff next to the amphitheatre.edit
Tumulii (singular: tumulus, in Turkish: tümülüs). These are conical not-so-high hills, rising suddenly out of ground and somewhat natural at first glance. They are actually man-made, remained from Thracians, the native folk of this region before the arrival of Greeks and Romans among others. They were erected to serve as mausoleum for Thracian kings and nobles (think of them as local variation of the pyramids, though these two are historically unrelated). Although the tumulii are scattered all around Thrace, the area about 5 km north of Marmara Ereğlisi has an exceptionally high number of tumulii, as Perinthos was an important centre of the region even before Romans. The tumulii 5 km out of town may not worth the trouble to go there, so you may take a distant look at a quite a few of them in the same frame when returning from the amphitheatre, just before entering the old town and immediately after the path swings to right (towards north).edit
Take a bottle of wine, go to the amphitheatre and enjoy it, perhaps against the sunset. The amphitheatre is so beautifully located that the sun sets exactly in the same direction the amphitheatre faces, beyond the sea.
As soon as you enter the town, you’ll see lots of signs for hotels (otel) and guesthouses (pansiyon). Some may be closed for winter, however, there are ones open year-round on the eastern waterfront.
If you are into camping, you can find some good and discrete spots away from houses to pitch your tent near the southern coast of the peninsula, over the cliff on the way to amphitheatre. Aim for areas covered with wild grass, not wheat fields or other cultivated places.
