Oliwa Cathedral (Archcathedral Basilica of the Holy Trinity)

Oliwa Cathedral, the Archcathedral Basilica of the Holy Trinity, stands at ul. Biskupa Edmunda Nowickiego 5 in the Oliwa district of Gdansk, in Poland's Pomeranian region. It is a former Cistercian abbey church, and its long Gothic nave is one of the longest of any church in Poland, giving the interior a sense of great depth. Visitors enter a calm space of pale vaults, side altars and tombs, with the abbey's history reflected in its furnishings. The most famous feature is the 18th-century Rococo organ, with elaborately carved and gilded decoration, in which angels and star figures move while the instrument plays. Short organ recitals are held during the day, and they are the main reason most visitors come. The sound and the moving figures make the recital the highlight of the visit, and it is best to arrive a little early to secure a seat with a clear view of the organ. Outside recital times visitors can walk through the nave and look at the chapels and monuments in a quieter atmosphere. A visit takes about one to one and a half hours, including the recital. The church is open daily, roughly from 09:00 to 17:00 or 18:00, with Sunday opening from 14:00, and entry outside recitals is free, while organ recital and festival tickets vary in price. The cathedral is best photographed from the west end looking towards the altar, though visitors should check the rules on photography and avoid disturbing worship. Weekday midday is a good time for the short recital, while summer weekends and festival days are busier. Dress modestly, as it remains an active place of worship. Oliwa Park is adjacent, so a visit to both makes an easy half day, reached by SKM train from Gdansk Glowny followed by a 15-minute walk.
