78.Marugame Castle Part2

Great stone walls, great view and the remaining Main Tower

Features

Today, Marugame Castle is open to the public as Marugame Castle itself or the Kame-yama Park. The range of the park is inside the Inner Moat. When you stand in front of the moat, you would be surprised to see the amazing high stone walls with the remaining Main Tower on them. The high stone walls are about 60m which is said to be the highest stone walls among other multiple tiers in Japan. (the highest in single tier is the stone walls of Osaka Castle which is about 33m high).

From Main Gate to Third Enclosure

Visitors usually enter the castle through the remaining Main Gate after crossing the bridge over the moat from the north. This gate has a typical defensive gate building style called Masugata. It consists of a square space surrounded by two gate buildings, mud walls, and stone walls.

Then, you will walk up on the long steep slope called Mikaeri-zaka or the Look-back Slope to the eastern direction. On the way of the slope, you will see the highest single tier stone walls in this castle which is 22m high of the Third Enclosure. In particular, the corner of the stone walls is very beautiful called the Slope of a Folding Fan which means its lower part is not steep, but its upper part becomes vertical.

You will eventually arrive at the eastern part of the Third Enclosure. You can see a great view of the Sanuki-Fuji from the ruins of Tsukimi-Yagura or the Moon Watching Turret.

From Second Enclosure to Main Enclosure

After that, you will enter the Second Enclosure between the Main and the Second Enclosures. The enclosure once had several turrets connected with mud walls like the Main Enclosure, now has a square with cherry trees and which local people are familiar with.

You will finally enter the Main Enclosure at the highest in the castle. A 360-degree view from there is so great. You can see not only the Sanuki-Fuji but also the islands and the Great Seto Bridge on Seto Inland Sea.

Devised Remaining Main Tower

The enclosure now has only the Main Tower, one of the twelve remaining main towers in Japan. It is a kind of three-story turret and, in fact, the smallest one among the twelve main towers.

However, it was improved in some points to look bigger than it is when looking up it from the foot of the mountain. The first point is the reduction rate to the top of the tower is relatively large. The second one is that the decorations of the tower like the hip-and-gable roof and the Chinese styled gable are facing outside. They help the Main Tower looks big from below.

You can also enter the tower and may feel it was made practical as a turret. The steps to upstairs are very steep. It equips machicolations and loopholes for battles. It also exhibits the historical explanation and miniature model of the castle now.

78.丸亀城 その2

素晴らしい石垣、景色と現存天守

特徴、見どころ

現在丸亀城は、丸亀城そのもの、または亀山公園として一般に開放されています。公園の範囲は内堀の内側となります。その堀の前に立ったとき、素晴らしい高石垣とその上に立つ現存天守の姿に驚かれるかもしれません。この高石垣は約60mの高さがあり、日本の多段式石垣の中では最も高いものと言われています。(単独の石垣で最も高いのは、大坂城のもので、約33mです。)

大手門から三の丸へ

観光客は通常、北の方から堀にかかった橋を渡り、大手門を通って城に入っていきます。この門は、桝形と呼ばれる典型的な防衛のための仕組みを備えています。2基の門の建物、土壁、石垣が四角い空間を取り囲む形になっています。

それから、見返り坂と呼ばれる長い登り坂を東側に向かって歩いて行きます。その坂の途中では、この城では単独で一番高い、22mの高さがある三の丸石垣が見えてきます。特に、この石垣の隅の部分はとても美しく、扇の勾配と呼ばれています。下の部分はそれほど急ではありませんが、上に行くに従い垂直に積まれています。

やがて三の丸の東部分に到着します。月見櫓跡からは讃岐富士の素晴らしい景色を目にすることができます。

二の丸から本丸へ

その後は、本丸と三の丸の間にある二の丸に入っていきます。この曲輪にはかつては本丸のように土壁によってつながれた櫓がいくつもありました。現在では桜の木が植えられた広場になっており、市民に親しまれています。

そして、ついにはこの城で一番高い所にある本丸に入ります。ここからは全方位の景色を眺めることができ、とても素晴らしいです。讃岐富士だけでなく、瀬戸内海に浮かぶ島々や瀬戸大橋まで見えます。

工夫されている現存天守

本丸には現在は天守しか残っていませんが、日本の現存12天守のうちの一つです。三層櫓の形式を取っていて、実は12天守の中では一番小さいものです。

現存天守(本丸から見える裏側)

しかし、山裾から見上げた時により大きく見えるよう工夫がされています。一つには、天守の上方に向かっての逓減率が比較的大きく設定されています。もう一つは、入母屋屋根や唐破風などの天守の装飾が外側に向かって付けられています。これらにより下から見たときに天守が大きく見えるのです。

天守の中に入ることもでき、櫓として実用的に作られていると感じられるかもしれません。上の階にあがる階段はとても急です。戦いのための石落としや狭間も備えられています。現代のものとしては、城の歴史や城の模型が展示されています。

78.Marugame Castle Part1

A castle covered with great stone walls with advanced technology

Location and History

It starts as Branch of Takamatsu Castle

Marugame Castle was located on a mountain called Kame-yama which means tortoise mountain in the western part of the Sanuki Plain of Sanuki Province (what is now Kagawa Prefecture). The part of the plain has several mountains that stood out like a projection, for example, Ino-yama Mountain is known for its beautiful appearance as Sanuki-Fuji. Kame-yama Mountain is one of the mountains and much lower than the Sanuki- Fuji ( 66m vs 422m), but was more convenient for the warriors to build a castle on it.

The Sanuki- Fuji

It is said that the Nara Clan first built a fortress on Kame-yama Mountan, but a castle named Marugame Castle was built on the mountain by the Ikoma Clan in 1597. The Ikoma Clan governed Sanuki Province under the Toyotomi Clan and the Tokugawa Shogunate later between 1587 and 1640. Marugame Castle was a branch castle of Takamatsu Castle which was the home base of the Ikoma Clan. However, Marugame Castle was once abandoned in 1615 in accordance with the Law of One Castle per Province by the Tokugawa Shogunate. The castle had unfortunately been destroyed as we found the wreckage of the old stone walls when the excavation was done.

Rebuilt by Yamazaki Clan and Kyogoku Clan

After the Ikoma Clan was transferred to another due to their internal trouble in 1641, the Yamazaki Clan was given the western part of Sanuki Province by the Tokugawa Shogunate. The Yamazaki Clan was allowed to rebuild Marugame Castle for their new home base. They built the high stone walls with three tiers covering all around Kame-yama Mountain. The stone walls were also built with advanced technology and very valuable because building a new castle was basically not allowed at that time. The re-construction continued for 30 years. The Yamazaki Clan was unfortunately fired by the Tokugawa Shogunate in 1657 during the construction because they had no successor. The Kyogoku Clan following the Yamazaki Clan completed the construction building the Main Tower by 1663.

It looks like Stone Fortress

The final appearance of Marugame Castle was as the following. The Main Enclosure, the Second Enclosure and the Third Enclosure were on the mountain. All the enclosures were surrounded by the stone walls making the very high ones stick together. The Main Enclosure, which was at highest, had the Main Tower and the four Corner Turrets connected with the roofed passages called Tamon or the mud walls. The Second and Third Enclosures were below the Main Enclosure and they also had several turrets. The Inner Moat surrounded the mountain, the Main Gate was just inside the moat in the north, and the Back Gate was in the south. In addition, warriors’ houses were built outside the Inner Moat and were also surrounded by the Outer Moat.

The Kyogoku Clan governed Marugame Castle and the Marugame Domain until the end of the Edo Period. In fact, the lord of the castle lived in the Main Hall at the foot of the mountain. That was a common way for the lords of the castles in peaceful time. Anyway, Marugame Castle must have looked like a stone fortress.
