Constructed in the 1420s (making it older than all the churches of Moscow’s Kremlin) the golden domed white church is the Trinity Cathedral, the last resting place of St. Sergius. The faithful can be seen queuing up here, sometimes for hours, to kiss the silver and glass shrine of the revered saint. The small cathedral is also filled with tourists craning their necks to admire the wonderful iconostasis partly painted by 15th Century celebrated icon master Andrei Rublev.
