The Boulder Dushanbe Teahouse is a cultural landmark and event venue located at 1770 13th Street in Boulder, Colorado. The building itself is a work of art: a 1987 sister-city gift from Dushanbe, Tajikistan to Boulder, its hand-carved cedar columns, Persian-painted ceilings, and eight exterior ceramic panels depicting the Tree of Life were crafted by more than 40 Tajik artisans working entirely without power tools. After a decade in storage, the teahouse was assembled in Boulder and opened in 1998, making it one of the most architecturally distinctive venues in the Rocky Mountain region. The teahouse hosts private events of all kinds — from intimate tea parties and bridal showers to weddings, rehearsal dinners, anniversary celebrations, Bar and Bat Mitzvahs, business meetings, and holiday gatherings. Three event areas are available: the ornate main teahouse, the Creekside Patio, and the Tea Garden. Full catering is provided by the venue's experienced culinary team, with menus spanning global culinary traditions.
