Tsar Chambers

The Tsar Chambers were erected in the late 17th c. By its outside appearance the edifice matches the Refectory Church. It was used by pilgrims from the royal family. In the 18th c. the Chambers vaults were decorated with fine stucco and carvings.  

The Church Archaeological Museum and the Holy Virgin Intercession Church are situated inside the Chambers. The wall paintings were created in 1987–8 by the iconographers of the local Icon Painting School. 

The church above the gateway, dedicated to the St. John the Baptist's Nativity, was built in 1693–9. At present confessions for pilgrims and exorcism are performed in it every morning.

Patriarch Chambers

The Patriarch (ex-Metropolitan) Chambers (1687–92) were built instead of the former superior cells. Nowadays, Patriarchs of Moscow and all Russia stay here during their visits to the Lavra. 

The top storey hosts a home church with the Holy throne consecrated in 1949 in St. Filaret the Pious' name.

The Patriarch Chambers adjacent to the Refectory Church were built simultaneously. Its facade made in baroque in 1778 formed the southern side of a small cosy square. The main entrance is decorated with columns which capitals support a balcony with an elegant forged lattice.

The top-storey front rooms feature rich baroque moulding and arch murals made in 1777–8 and old tile stoves with a vegetable ornament.

Moscow Theological Academy

The Moscow Theological Academy and Seminary is the highest instutute of the Russian Orthodox Church stemming from the Slav-Greek-Latin Academy (1685). The pious Empress Elizabeth who often visited the Trinity Monastery founded the Seminary in the Tsar Chambers in 1742. The Academy trains Orthodox priests.

In 1814 the Theological Academy was transferred from Moscow to the Lavra, and a new complex of buildings for school needs appeared. Its yellow classroom building was erected in 1839 and got a 3rd storey in 1884.

At present the Tsar Chambers belong to the Academy. Academy access is for its students only. 

Hospital Wards

The Hospital Wards with the St. Zosima & St. Savvaty (Sabbatius) Solovetsky Church (1635-7) are a rare existing example of medieval civil architecture. Between the 2-storey Hospital Wards stands a steepled church - unique for the Lavra. It's also the only church here built simultaneously with the surrounding stone wards hosting the monastery clinic. The church features orderly proportions and expressive facade decoration with plenty of green glazed tiles.

The Assembly Chambers with the St. Zosima and St. Savvaty Church were constructed by monastery cellarer Alexander Bulatnikov who had come to the Lavra from the Solovets Monastery. Before 1917 the building was used as a hospital for sick monks and an almshouse for the old and disabled. The church is seemingly patterned after the no-more existing Pokrov Cathedral of the Solovky. Now this complex also hosts the Lavra vicar ward.
