| Base-area relationship | Historical island / riverside |
| Access logic | Use as a route/base-area stop; exact hours, ticketing, closures and ceremony restrictions should be live-checked. |

Sources and verification
Temple identity, heritage status, visitor access, and ceremony arrangements come from different sources. This guide keeps those roles distinct rather than treating one listing as complete proof.
Source list researched: 24 August 2026. Opening hours, fees, ceremony access, dress rules, and closure notices may change. Confirm them with the individual site or responsible authority before a fixed visit. Report a factual correction.
