3.1 Distribution of Historical Monument Sites
The Fine Arts Department has 136 historical monument sites and
listed 411 historical monument sites altogether from 1935 until the
present [18]. The total study area covers 102.97 square kilometers.
199 historical sites are within Ayutthaya Island and 290 are around
Ayutthaya Island. The study area of HMS was divided into six
zones, the most important area which has the best physical
development and atmosphere is (1) the Nucleus Zone, while (2) is
an area with less importance in the City Island and the other four
of six areas are the Buffer Zone outside the city Island. The
distribution of the 489 HMS in the study area (115 registered HMS
and 374 listed HMS) is shown in Table 2. The distribution of HMS
coordinated by Global Positioning System (GPS) was used to take
coordinates of locations of HMS, as shown in Figure 4.
