**Step 1:** Start building the main frame with this Archway structure starting from the 5th screenshot. Use large archway pieces and add one crown block for the lower two archways before building the next one on top. Later it will make the archway look better after adding a column for the finish.  
**Step 2:** Expand the main frame by repeating the same archway structure on both sides, starting from the center of the tip and work down in reverse.

**Step 3:** Now we will start on epanding the frame around the center, starting from the base of the columns. Use archway crowns to create the corners. (Using the regular granite is easier because that set has a crown pieces of 3 blocks in length where marble and sandstone only have single piece crowns)  
**Step 4:** Place more crownpieces to form this pattern. They will be used to connect more archways to like how we started the main frame.  
  
**Step 5:** Now we go finish the frame on the first level. Place 7 more archways on one side, placing the last 2 one block more inward than the first 5. This will create a nice pattern on the inside.  
**Step 6:** How it should look now on the inside.  
**Step 7:** Repeat step 5 so it will look like this.  
**Step 8:** The inside of the corner should look like this now. See how the 4 inner archways form a neat pattern. :)  
**Step 9:** The next step is placing 4 Narrow Crafted Wall pieces like on the screenshot.  
  
**Step 10:** We will continue on the second level with placing archways. Place 5 archways like we did on the first level but now place the 4th and the 5th one block more inward.  
**Step 11:** Repeat step 10 on the other side of the corner.  
**Step 12:** Result of step 10 and 11 from the inside!  
**Step 13:** Add a column base on the ugly corner to make it look better and add 4 more shafts on top of this one.  
**Step 14:** Place 4 narrow crafted walls like on the screenshot.
