LANDLOCKED MICROSTATE · HILLY TERRAIN · MOUNT TITANO · TEMPERATE BIOCLIMATE
San Marino is a small landlocked state entirely enclosed by Italy. Its 61.19 square kilometres rise from about 55 metres to 739 metres above sea level, with Mount Titano forming the dominant relief feature. This profile keeps the architecture selective: modules that do not fit San Marino, or lack sufficiently strong current data, are omitted rather than filled with weak estimates.

Major streams
Ausa · Marano
The official flora study identifies the Ausa and Marano as two principal streams in the north-eastern part of the territory.
South-west drainage
Marecchia
The south-western side of Mount Titano lies in the Marecchia river basin; the San Marino stream joins it in Italian territory.

Official and technical classifications
01
Temperate macrobioclimateThe 2022 flora study classifies San Marino's macrobioclimate as temperate.
02
Oceanic bioclimateThe same study describes an oceanic bioclimate with a sub-Mediterranean variant.
03
Three winter zonesThe 2014 law defines ZCI-1, ZCI-2 and ZCI-3, spanning 2,086 to 2,940 heating degree days.

Understand the landscape
What San Marino's geographic profile is telling you
San Marino demonstrates why this vertical cannot force one fixed set of cards onto every country. The state has no coastline or island chain, so those modules disappear entirely. Its useful physical story is instead about relief, Mount Titano, small stream systems, geological diversity and a climate that varies with elevation across a compact territory.
The environmental data also need stricter date handling. A useful land-cover breakdown is available in the 2022 flora publication, but the underlying mapping is from 2009. The page therefore labels it as a historical reference rather than disguising it as current data.
Why there is no coastline module
San Marino is landlocked. A zero-value coastline chart would add visual noise without improving the physical-geography explanation.
Why some environment cards are absent
No greenhouse-gas, protected-area or renewable-electricity headline is forced into this proof page when a sufficiently current, directly supportable value was not identified during the source pass.
Detailed Geography & Environment Data
The table keeps directly sourced physical facts separate from older land-cover reference data so readers can see what each figure actually represents.

Frequently Asked Questions
How large is San Marino?
San Marino covers 61.19 square kilometres.
What is the highest point in San Marino?
The technical geography source used on this page places the highest point on Mount Titano at 739 metres above sea level.
Is San Marino landlocked?
Yes. San Marino is entirely enclosed by Italy and has no coastline.
Why are some environmental indicators not shown?
DigifyWorld omits country indicators when a sufficiently reliable and appropriately dated source is not available instead of filling the page with weak estimates.
