Type II
It has a series of receding terraces, surmounted by a cylindrical or bell-shaped dome which continues into a finial of concentric rings.
In the developed form of this type, there are three receding square terraces and an octagonal base providing the transition to a bell-shaped dome with a band of moulding in the middle.
The Lawkananda and Shwesandaw provide early examples of this type, while the Shwezigon and Mingalarzedi are prominent representatives of the developed form.

Type III
It is similar in basic form to Type II, but has a ribbed, bowl-shaped disc, interposed between the dome and the finial. An example is the Seinnyet Nyima.

Type IV
This is modelled on the medieval Sinhalese dagaba or Pagoda, has a bell-shaped dome on a circular base, and a box-like relic chamber interposed between the dome and the finial. The Sapada is an outstanding example of this type.
Other than the above four, the architectural types at Bagan may be further classified as follows: |
