Don't confuse this church with the other St. Nicholas, in Mala Strana. The 18th-century, twin-towered edifice of this church looks larger from the outside than it really is. The constraint on space meant that the towers were placed on the long, southern flank of the church rather than, as is usually done, on the shorter western façade. This church has a gorgeous late-baroque interior and concerts here often center around the massive organ at the rear. Concerts are held daily in the summer. Note that the musicians usually stand out of sight in the organ loft. The acoustics here are superb enough to make even a middling soprano sound great.
