There are 3 entrances to the Wat Langka complex, with the main entrance off Sihanouk Boulevard. This entrance leads to a courtyard, with a temple under renovation (and thus closed off) to the left, an admin-type building to the right and the main temple in front.
I would highly recommend reading up on temple etiquette as there was a guy in front of me who had the monks (gently) yelling at him – a simple tip is take your shoes off before you step inside the temple!
Anyway, the main temple was pretty cool – a large centrepiece of Buddha in a large, quite open hall. The highlight is the artwork on the walls and ceiling – some lovely images. All in all this is a great temple – very close to the Independence Monument. Don’t expect English signs, but the monks were friendly and helpful, so if in doubt just ask.
