There are 266 (some add: and 2/3) amos in a "ris," a measurement used for some halachic purposes (such as the distance you have to go to aid someone whose animal has collapsed under its burden - Bava Metzia 33a).
[R' Y.Y. Keller once suggested to me that the oddity of this figure might be explained by assuming that an amah is exactly 1-1/2 feet (not necessarily the same as the foot in the American system of measurement, though), in which case this makes a nice round figure of 400 such feet.]

In a leap year, Yom Yerushalayim is the 266th day in the year if Heshvan and Kislev are both Mele'im (have 30 days):
Tishrei, Heshvan, Kislev - 30 days each
Tevet - 29 days
Shvat - 30 days
Adar A - 29 days
Adar B - 30 days
Nisan - 30 days
Iyar - 28 days (Yom Yerushalayim is on the 28th day of Iyar)
