Phra Sumen Fort

ป้อมพระสุเมรุ

Best viewed from Santichaiprakan Park, Phra Sumen Fort is one of two remaining towers of the historic city wall that once surrounded Rattanakosin Island completely (the other being Mahakan Fort). The historic city wall that followed the Chao Phraya River and Khlong Rop Krung used to have fourteen of these watchtowers, but twelve of them have not endured the test of time. Phra Sumen Fort was constructed in 1783 during the reign of King Rama I to protect the city from potential foreign naval invasions. The fort has an observation tower and two levels of battlements with its original canons still in place.

Roti-Mataba
This immensely popular eatery is one of the few in the area serving Thai-Muslim dishes, such as roti, mataba (a kind of stuffed pancake) and massaman curry. Sitting downstairs gives the best local experience, as you can smell the food being prepared and it feels very cramped. Upstairs has air-conditioning and is more comfortable. A bit of a downer is that the snacks are fairly small, so order two or more meals if you are really hungry.

Santichaiprakan Park
พระที่นั่งและสวนสาธารณะสันติชัยปราการ
This small, green park has a great view of the Chao Phraya River and the modern Rama VIII suspension bridge that crosses it. There's an open-air pavilion, the Phra Sumen Fort and (supposedly) the last two lamphu trees of the area (these trees used to be all over Banglamphu, as that's where the district got its name from). Activities held in the park include Thai classical music, juggling and (at 18:00) aerobic exercises. The park has also become a gathering place for breakdancers to exchange their techniques.

Aquatini Bar & Restaurant
ร้านอาหาร อควาตินี่ บาร์
Part of the Navalai River Resort, this luxury restaurant with Thai and Western dishes has river views over the Chao Phraya River. The interior of the indoor bar has random postmodern touches. It's best to stick to outdoors though, as the deck gives the best views. The breeze, trees and light music make the ambience chilled out. Mostly foreigners visit this place, and the staff make it feel a bit like being inside a resort (well, which you are). The kitchen sure knows how to keep their dishes true to the Thai tongue, though. Try the tom kha kai — it's whiter than white.
