The castle was abandoned only five years after its construction due to the Tokugawa Shogunate's 'One Castle per Province' edict.
The park's moat accounts for roughly one-third of the total site area, providing a natural habitat for various water birds.
The park contains the Takaoka City Museum, which displays artifacts excavated from the castle ruins and regional historical materials.
The stone walls found within the park are notable for their 'uchikomi-hagi' style construction, intended to withstand earthquakes.
The main entrance path follows the original route leading to the castle's former primary gate, the Otemon.
The park layout has remained largely unchanged since the early 17th century, preserving the original strategic defense lines.
Takaoka Old Castle Park is built on the former site of Takaoka Castle, a fortress constructed by Maeda Toshinaga in 1609. The park features a preserved moat system that remains largely intact, encircling the inner grounds. It is designated as a national historic site and serves as a significant urban green space in Takaoka. The park landscape includes approximately 1,800 cherry trees, primarily Yoshino cherries, which bloom in early spring. During autumn, the park grounds are noted for their vibrant foliage. The ruins consist of earthen ramparts and stone walls rather than standing castle structures. A central park area provides space for recreational activities and seasonal events. The site is recognized for its connection to the Kaga Domain's history and the early development of Takaoka city.

Walk the entire perimeter of the moat for a comprehensive view of the earthen fortifications.
Visit the interior paths away from the main road to find quieter, wooded sections of the park.
Do not attempt to climb or walk on the protected earthen ramparts to prevent erosion of the historic terrain.
