Matsumoto Castle

松本城

Original keep

Matsumoto is a flatland castle with an original keep reflected in its moat. Comparing its defensive towers with the later Moon-viewing Turret reveals a change in architectural purpose.

THE STORY

The story behind the walls

The site developed from Sengoku-period Fukashi Castle. Under Ishikawa Kazumasa and Yasunaga in the late sixteenth century, the castle and keep complex took their later form. Research places construction of the main keep and associated early structures around 1593–1594. Edo-period additions included the attached and Moon-viewing turrets, creating the surviving National Treasure group.

LAYOUT & ARCHITECTURE

Read the landscape and the buildings.

The connected keep complex stands on masonry beside a moat in a flatland setting. Understanding five external tiers and six internal floors is a first step to reading the structure. Defensive early buildings and more open later additions can be compared in one ensemble.

A CLOSER LOOK

Details worth a closer look.

01

Five roof tiers, six floors

The visible roof tiers do not equal the number of internal floors. Knowing that the main keep has five tiers and six storeys changes how its exterior is read.

02

Five connected buildings

The main keep, smaller tower, connecting structure, attached turret and Moon-viewing Turret form one group. It is an interconnected complex rather than a single isolated tower.

03

Moon-viewing Turret

The later Moon-viewing Turret differs from the defensive keep. Its more open design reflects a different purpose and a more settled age.
