A small castle, just beside the Parliament House across the river, take the small ferry 1rm and walk for about 10 minutes. It takes 45 minutes to walk through a forest garden by detour to walk through the bridge (estimated because of the maintenance of the Parliament House, it is very far), or the ferry is convenient. Tickets are MYR 20, which is a museum. People who like history can go in and see, and the introduction is more detailed.
