Teimiussa lies directly east of today's village of Üçagiz, you can visit some of the ruins at the eastern end of Üçagiz's harbour.
Not much is known about the history of the city and it has no known coinage. Tombs with Lycian inscriptions point to settlement by the fourth century BC. The city seems to have had ties with Myra and Cyaneae. An ancient road leads directly from it to Cyaneae and some of Teimiussa's tombs bear inscriptions saying that they belong to citizens of Cyaneae and Myra. Teimiussa was probably a small settlement tied administratively to these two cities.
The main ruins here are a necropolis to the east with a large cluster of sarcophagi, mainly from the Roman period. The oldest ruins are a few rock-cut house-type tombs at the eastern end of Üçagiz's harbour. One of these has a relief of a nude young man and an inscription tells us that the tomb belonged to a person named "Kluwanimiye".
At the eastern end of the city is a large dock, 28 metres long and 8 metres wide, carved out of living rock
