Nanzen-ji Temple — Zen and Aqueduct Architecture

Nanzen-ji (南禅寺) ranks as the head temple of the Rinzai Zen sect's Nanzen-ji school, with a massive Sanmon gate (三門, 22 meters tall) offering panoramic city views from the upper story. The temple is famous for its surprising brick aqueduct (Suirokaku, 水路閣) — a Meiji-period (1890) Roman-style aqueduct that cuts through the temple grounds, still carrying water from Lake Biwa to Kyoto.

The temple's sub-temples include Nanzen-in with its pond garden, and Konchi-in with a famous rock garden. The grounds are sprawling (multiple sub-temples spread across 100+ acres), requiring 2–3 hours to explore fully.
