When I first saw the Koryu (currently Houlong) Airdrome Plan in the 1945 Taiwan Area Airdrome Plans, four areas, marked A to B in the above map, immediately drew my attention. Although I tried to cover as many of them as possible during the excursion the other day, I did not make it to area B because 2.5 hours of continuous walking made my legs very sore and there was not enough time left. The following Google image shows the route I took (the green curves) and the points where I took the photos (indicated by numbers).
There were buildings and installations of unknown purposes in the following 1945 reconnaissance photo of Area A:
This is what Area A looks like today:
At location No. 1, I found what could be the entrance to an air raid shelter:
Since the Japanese specifically built a road to Area C, it should have been a location of some importance. Unfortunately I do not know its real purpose:
The following photo taken at location No. 2 shows that Area C was located on a small hill. The trail must be based on the road built by the Japanese.
I found several old brick houses at No. 3 location. Although they appeared aged, I doubted they were built by the Japanese because they did not look THAT old. They could have been built after the war.
Area D was encircled by a road in 1945. Another straight road led to the main taxiway:
The following photo taken at location No. 4 revealed that Area D was also located on a small hill:
Before I left for the train station, I passed by the west side of Jen-Teh Junior College of Medicine, Nursing and Management. There used to several aircraft revetments in the past:
I ran into this pillbox at location No. 5:
Unfortunately it had cut in halves:
At location No. 6, there was this mound, which I suspected was part of an aircraft revetment:
There is a Kamikaze Part at location No. 7. I am not sure if it was for the Kamikaze that was rumored to be stationed at Koryu Airdrome. Anyway I could not find plausible evidence to confirm this.
