Tbilisi in 4 days

Around ten bathhouses sunk below low brick domes in the district where the city began, fed by sulphur water that emerges at 38 to 40°C.

A narrow gorge behind the sulphur baths, cleared and given a walkway in 2012, leading to a twenty-metre waterfall in the city centre.

A citadel above the old town begun in the 4th century; a powder explosion in 1827 destroyed part of the walls and St Nicholas church.

Steep lanes beneath Narikala lined with carved wooden balconies, often leaning, in a quarter rebuilt many times, including after the Persian sack of 1795.

A flea market born in the 1990s after the Soviet collapse, selling silverware, Soviet watches and cameras, medals, porcelain, records, samovars and old maps.

A 150-metre footbridge over the Kura by Michele De Lucchi, opened in 2010, whose LED canopy spells out messages in Morse code at night.

Built from 1995 to 2004 on Elia Hill for 1,500 years of Georgian Church autocephaly, one of the world's tallest Orthodox cathedrals.

A funicular of 1905, restored in 2012, climbs the holy mountain; halfway up, the Pantheon holds the graves of Griboyedov and his wife Nino Chavchavadze.
