I had a curiosity to examine the ancient monuments at Tyr, opposite the mouth of the Amgoon river, but we passed them in the night without stopping.

There are several traditions concerning their origin.

The most authentic story gives them an age of six or seven hundred years.
They are ascribed to an emperor of the Yuen dynasty who visited the mouth of the Amoor and commemorated his journey by building the 'Monastery of Eternal Repose.' The ruined walls of this monastery are visible, and the shape of the building can be easily traced.

In some places the walls are eight or ten feet high.
Mr.Collins visited the spot in 1857 and made sketches of the monuments.

He describes them situated on a cliff a hundred and fifty feet high, from which there is a magnificent view east and west of the Amoor and the mountains around it.
