Explanation:

- Dedicated: This word fits the context well. It means something that is set aside for a special purpose, especially to honor someone or something. A memorial is typically dedicated to those it aims to honor. The National war memorial is dedicated to our Armed Forces.

- Devoted: While this word conveys commitment and love, it is not generally used for physical entities like memorials. It describes emotional or moral loyalty.

- Honoured: This indicates showing respect, but is not commonly used to describe the relationship between a memorial and its subject.

- Inscribed: This involves writing or engraving words, often used for detailing names and messages on a memorial, but not for describing the entire memorial itself.
