Located around the periphery of the Red House plaza is the Ximen Market, which was Taiwan's most fashionable commercial district for daily-use products back in the Japanese occupation era, and was also once the biggest wholesale food market on the whole island.
而紅樓周邊的西門市場，除了在日治時代是全台最流行時髦的日用百貨商圈，也曾是台北最大的食材批發市場。
